Quiz in zoom webinar rewarding

Hi! 

In my webinar we have usually some presentation and after I prepare for participants questions in Poll or quiz. 

The participants answered the questions and we can see the right answer. 

But my question is: How I can choose for example 1 or 3 participants with right answer to give or send them present.  Because now I see only how many participants answered correctly. I don't see the name.  How can I choose the only one - the winner.  It is possible in zoom webinar?  Thanks.
