Can’t add poll to my slideshow

I want to add a poll at the end of a series of pictures but the option isn’t there. Do I have to make a video with the images running as a slideshow for this to work?

I have text on the images and want people to swipe through as they read the text so that people don’t click off if it’s taking to long.

Would another option be to add comments with the options and ask for likes on the comment option they vote for??
