Is there any possibility to create a poll in the connector "Post a message as the Flow bot to a channel"? Or as response to the message in teams channel. I need a poll so that users could choose their opinions there and see results of the poll.
Yes, should be possible. I would use a different action though, the Post your own adaptive card as the Flow bot to a channel:
Also have a look at the Poll Generator sample from Microsoft Docs:
Let us know if you need any additional help with the configuration.
@Expiscornovus thanks for the response. I cannot use the adaptive card connector because I post some data with the connector "Post a message as the Flow bot to a channel" and there is a html table. As far as I know, that's not possible with the adaptive card connector to post something else like HTML table that I need anyway.
