We have successfully configured the Microsoft Teams app in Splunk SOAR, and we are able to send messages to a Teams channel, but the messages are coming from the account of the Azure Global Admin who created the App Registration and granted the permissions. Within the Asset Configuration in Splunk Soar, we have tried to use different users under the "Select a user on behalf of which automated actions can be executed (e.g. test connectivity, ingestion)" setting without success. How do we configure the app to send from a different user?
