Optional Body Section needed for OAuth 2.0 authentication

Hello, I’m trying to using Azure Resource Manager REST API with REST Connector to look for improving Infra Management using Camunda.
After successful postman test, I tried to call using REST Connector but the following error thrown :

The access token has been obtained for wrong audience or resource '00000002-0000-0000-c000-000000000000'. It should exactly match with one of the allowed audiences 'https://management.core.windows.net/','https://management.core.windows.net','https://management.azure.com/','https://management.azure.com'."

Some discussion like Azure AD Audience / Resource - Stack Overflow tells that the request header should includ ‘resource’ as https"//management.azure.com/ But there is no space to add this in REST Connector authentication section.

Is there way to add it?
