Can Co-Host launch a poll?

From the description in this article, it implies a co-host can see Polling to launch a poll. https://support.zoom.us/hc/en-us/articles/201362603-Host-and-co-host-controls-in-a-meeting

We just did a test and promoted someone to co-host in the webinar, and they don't see the polling option. We even promoted them to host and they still don't see the polling option (the original webinar host does see the polling option).

We can't pre-define the co-hosts as we are using the same webinar for several sessions, but would like co-hosts to be able to launch the polls. Is this possible? 

Thanks,

Tammy
