Is there a way to post an adaptive card to a teams channel where it doesn’t appear with the “sender” as the user. I realize I could use a service account but that service account would require a license. For the Outlook action I can send as someone else (a group mailbox) as long as I have rights to that mailbox - is there something similar with posting an adaptive card.
I don’t think so, the option to post as the Flow Bot names the person that ran the flow. I believe (but not 100% sure) there used to be an option to do this years ago, but it seems to be gone now.
So I think you would have to use a service account
