As far as I know, when the meeting is over, the only feedback users can give is quality feedback (1-5 stars).
To get this feature more quickly, I have found a feedback in Teams UserVoice and you could vote for it. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding and support.

If you schedule a meeting in a channel, you could create a form using the Forms bot, just type @forms, you could also do that in the meeting chat after the meeting. You should send it
manually to all participants.
