Adding an Invitee Email to an Calendar Meeting Scheduled by Booking Page

My company uses Gong and it will only recognize a meeting when it shows an external invitee.  I am assigned staff from a business booking page and I am also the Administrator.  When a person books a meeting, the meeting notice I receive doesn't list that person as an invitee.  I am the only invitee.  I need to add the email for the person booking the meeting to my Outlook calendar entry to enable Gong because Gong also is responsible for populating the event to our CRM system.  Can someone help with this issue?  I am not allowed tohadd any invitees or change the meeting information in the Bookings created meeting.  I'm happy to manually enter the invitee; I just need the option to do so enabled.
