with that I can get one line for a reource group my-grp
resourcecontainers
| where resourceGroup contains 'my-grp'

You can use the following Azure Resource Graph (ARG) query to get all types of resources for a particular resource group.
resources
| where resourceGroup == 'yourResourceGroupName'
| project type
