@denisebmsft or @chrisda Is there any additional documentation that you can provide for all the possible field values for EndpointCall? It would be ideal to know all the possible field values and what they represent in terms of the authentication flows.

I will follow up with the PM!

@schmurky thanks! :). I got a lot of use so far from this table while testing the beta, and would love to get some more details on this field and its possible values.

Hi @schmurky , has there been any update on this one?

Hi @schmurky , just following up on this PR since it's now 2 months old with no updates from the Microsoft side.
