Polling with live view of who has responded

I am a software instructor switching to teams for our online instruction. Throughout our training we have students do several exercises in our software. We currently use WebEx and it's polling feature where students can respond when they've completed their exercise. This allows us to see who has responded (I'm finished) and who hasn't (I'm still working). I'm trying to replicate that in Teams.
Using Forms polling in Teams doesn't allow me to see responses until the poll is closed. I can use simple hand raises, but that is visible to all students and I'd rather it be only be visible to the presenter.
Does anyone know if a way to accomplish this?
