Zoom Events - Exhibitor's Representative Emails

Hi Folks,

This past week, I have been having trouble with getting the "representatives" in the exhibitors to receive access to their virtual booths. It appears that the "Exhibitor" invitation, through communication/emails, only sends to the exhibitor contact. I then tried sending in special roles, and only half of the representatives received emails. If they received the email invite from  it asked them to log-in. Everyone's email was inserted correctly (we checked that together).
 
I could only find this support article, yet it did not help me answer my questions below.

My two questions are as follows:
1) Do representatives in the exhibitors need to download the Zoom desktop client?
2) Does anyone know a workaround in getting representatives, not exhibitor contact, an email with their "join" link?

Many thanks,

Syd
