Hello Diana, method are you currently inviting your panelists? There are a couple of different methods you can either forward the  attendee a meeting link then promote them to panelists:

Promoting an attendee to panelist

2. Start a webinar as the host.
3. Click Participants 
    

    

4. Click the Attendees tab.
5. Hover over the name of the attendee you want to promote and click More.

Another option is to manually add the panelist (this will send them a separate link)

1. Sign in to the Zoom web portal.
2. Click Webinars. 
3. Click the topic of the webinar you want to add panelists to
4. On the Invitations tab at the bottom of the page, find the Invite panelists section and click Edit.
