Enable SQL MI logs related database drop/delete activity

We have an Azure SQL MI having number of databases on it . We have to enable audit logs of SQL MI from diagnostic settings and also enabled logs by executing queries on MI and sending those logs to event hub. We are getting up logs (select, Execute) but not able to see the logs related to database drop/delete activity

the blog (https://docs.imperva.com/en-US/bundle/cloud-data-security/page/78051.htm) I am using the for enabling audit log in Azure SQL MI, what I am missing any step plus we need to see/visualize the data/request that are coming to eventHub.
