• virtual entities only work with the highlighted options on the connection:
• Azure AD integrated
• SQL server authentication
• windows authentication
• service principale
• The windows ones are for On Premises , so that leaves us with AD integrated and SQL Server Authentication.

so we can conclude that using the clientID/secret doesn't work with Virtual entities for cloud environments.

the connection can be created but cannot be choosen when creating the entity.And on changing from the inside it doesn't connect and returns null data.

would like to be able to select the created ClientID/Secret connection when creating virtual entities.
