Accessing Polls

I created some polls in advance of a workshop I was going to facilitate on Zoom.  Normally, when I set up the Zoom meeting myself, I'm able to see the option to launch polls for the audience when I'm in the meeting.  In this case, however, I was not the one to set up the Zoom meeting - someone else did so I was not the main host.  When I joined the Zoom meeting, the host made me a co-host.  I went to launch a poll, but discovered the Poll feature was not available for me.  It did not show up in the main tool bar or under the "More" section.  I've had this happen before and don't understand why I can't access the polls I set up in advance when I'm a co-host even if it's for a meeting I didn't set up originally.
