Show several panellists while screen sharing in Webinar

Hi, I am hosting a webinar this week and need to work out how I can show several panellists while on a screenshare in Zoom Webinar.

I know it can be done as we have previously oursourced to a provider to run these events and they had their settings to there was a gallery of our Board members that could be seen even while screensharing slides. Our Board expects to be visible to our shareholders during the meeting. 

I tried it today in a practice but when the screenshare is on, attendees can only see the speaker/person I spotlighted.

Help!
