@Asif is it possible to use Self-configured approach for this integration instead of a pre-published app from ServiceNow?

@Raguram1  very helpful article. Is it possible to use Self-configured approach for even EC Pro integration with MS Teams? The one referred in below article. Unable to find appropriate documentation for it.https://www.servicenow.com/community/ms-team...

Need more details like how table are linked, screenshot of EDIT button when impersonating end user, etc.

Use "Left Join=True" on one of the table. Try changing the order and where clause based on your custom table design.
