When I create a channel, I use application permissions.

But why do I need delegated permissions to provision the channel's emails?

Please let me know if there is another way to avoid using the delegated permission.

Answer 1

It's simply not supported. The only other way would be to use the Teams client itself, which is again in the context of a delegate.
