[SOLVED] Orion context broker doesn't create tenant databases "on the fly"

I created and ran fiware-iot-agent in docker container along with fiware-orion context broker. The mongoDb Im using is a sharded cluster with 2 shards and auth-enabled. I verified that orion is connecting to the cluster. Below is the docker-compose.yml Im using.

version: "3.8"
services:
  # Orion is the context broker
  orion:
    image: fiware/orion:${ORION_VERSION}
    hostname: orion

    command: -dbhost 192.168.2.5:27030 -dbuser $DB_USER -dbpwd $DB_PWD -dbAuthDb admin  -db orion -logLevel DEBUG
    healthcheck:
      test: curl --fail -s http://orion:${ORION_PORT}/version || exit 1

My problem is when I add a new device to the fiware using endpoint http://localhost:4041/iot/devices it creates a database named iotagentul and a collection named devices in it. The device I added is being saved to this collection. So far so good. But Im expecting another database to be created when I add a new device. In orion docs it says this:

Normally, Orion Context Broker uses just one database at MongoDB level (the one specified with the -db command line option, typically "orion"). However, when multitenant/multiservice is used the behaviour is different and the following databases are used (let be the value of the -db command line option): The database for the default tenant (typically, orion) The database - for service/tenant (e.g. if the tenant is named tenantA and default -db is used, then the database would be orion-tenantA. Per-service/tenant databases are created "on the fly" as the first request involving tenant data is processed by Orion. Finally, in the case of per-service/tenant databases, all collections and administrative procedures (backup, restore, etc.) are associated to each particular service/tenant database.

So according to this there should be other databases which will hold the entities for the devices. But they are not showing up. I tried with a mongo without authorization but its still same. How can I solve this problem? Any help is appreciated.

Edit: My request body is shown below:

    {
 "devices": [
   {
     "device_id": "PA_TALASLI1",
     "entity_name": "PA_TALASLI1",
     "entity_type": "power_analysis",
     "transport":   "HTTP",
     "timezone":    "Europe/Istanbul",
     "attributes": [
       { "object_id": "Voltage_UL1_N", "name":"Voltage_UL1_N", "type":"Double"},
       { "object_id": "Voltage_UL2_N", "name":"Voltage_UL2_N", "type":"Double"},
       { "object_id": "Voltage_UL3_N", "name":"Voltage_UL3_N", "type":"Double"},
       { "object_id": "Current_L1", "name":"Current_L1", "type":"Double"},
       { "object_id": "Current_L2", "name":"Current_L2", "type":"Double"},
       { "object_id": "Current_L3", "name":"Current_L3", "type":"Double"},
       { "object_id": "Total_Active_Power", "name":"Total_Active_Power", "type":"Double"},
       { "object_id": "Total_Reactive_Power", "name":"Total_Reactive_Power", "type":"Double"},
       { "object_id": "Total_Power_Factor", "name":"Total_Power_Factor", "type":"Double"},
       { "object_id": "Total_Active_Energy_IN_T1", "name":"Total_Active_Energy_IN_T1", "type":"Double"},
       { "object_id": "Total_Active_Energy_IN_T2", "name":"Total_Active_Energy_IN_T2", "type":"Double"},
       { "object_id": "Total_Active_Energy_EX_T1", "name":"Total_Active_Energy_EX_T1", "type":"Double"},
       { "object_id": "Total_Active_Energy_EX_T2", "name":"Total_Active_Energy_EX_T2", "type":"Double"}
      ],
      "lazy":[
        { "object_id": "Voltage_UL1_N", "name":"Voltage_UL1_N", "type":"Double"}
      ],
      "static_attributes": [
         {"name":"refStore", "type": "Relationship","value": "urn:ngsi-ld:pa_talasli1:001"}
      ]
   }
 ]
}

I tried running the container with log level debug but I didnt see anything about the entity creation. If I add a lazy attribute to the body, it creates a table named registerations but there is no entities table. I specifically created an entity through /v2/entities/ but what I need is to have entities be created after I add a new device to /iot/devices
