I am using the"Post adaptive card in a chat or channel" box to give people notifications about approvals in a place they will actually action them.

If the approval updates (expires, cancels etc...) I want to be able to update the adaptive card so people dont try approving cancelled approvals.
The problem is, the update adaptive card in chat or channel block does not allow me to select the "chat with flow bot", only channel or group chat, see below.

So I dont seem to be able to access the card that I posted to the user who has a potentially cancelled approval in there, to show that the approval is no longer valid.
Am I missing something here? can anybody think of a work around?
Many thanks!
