How to test out a poll in a practice session and join as a participant

[Zoom-User2]

Hello,

We would like to test out a poll in a practice session, a few days before the webinar. The practice session would be used a second time, just before the webinar.

Apparently, if we test it out, the poll will be deactivated. Is it possible to recreate the poll after the practice session? Also, I don' t know how to join the practice session as a normal participant  to see how the poll looks like. Is there a way to get this view? 

Thank you.
