The idea of the "focus poll" is precisely for the owners or admins of groups or channels, when they need to collect some important data from their members or followers with a certain "urgency".
The idea is that when the "Poll in focus" option is selected when creating the polls, when the members of groups or channel followers enter for the first time right after the poll is posted, it will be over the text of the group or channel, focusing first to vote in the poll.
For those who don't want to answer the poll right away, just drag it down in the chat, where it will be hidden in an extra and large button above the text box of the app that says, "Vote in the poll", in which this big button would be flashing or with a bit more bright than the chat, to get attention.
Then you can if the person who temporarily waived voting in the poll, to respond to a message quickly (in groups) can pull this button up to respond to it right after. Also using the idea I suggested in the following post.
You can make a group of "focus polls" and go through them one by one by swiping the following polls to the right or returning the previous ones by swiping to the left. After you have completed all of them, in the last poll selected for that group "surveys in focus" a "Finish" button will appear. (In which that glowing button that would have been above the text box will be gone).
