Invoke activity is not sent when consent card button is clicked

[DanielTitkov]

I've tried to run file-upload example from the repo. It runs, but when I click "accept" or "decline" on the consent card nothing happens. Nothing appears in logs after the information about "message" activity is being processed. Seems like nothing is sent from teams whatsoever. I've tried both web and desktop teams client. Other activities are processed as expected.

Should I configure my bot is some special way in order to have "invoke" working? Or maybe consent card in the example is not correct?
