Does a Co-host for a Webinar need license?

[MileHi]

So we just signed up for an account for our Meetup group 300+ users with a meeting/webinar coming up of about 120 participants. We decided to go the webinar route to get past the 100 person limit. Of course we's like to have helper for the event - co-hosts but do they too need to have a license? I know MEETINGS can have unlimited co-hosts but I don't see a way to add a co-host, covert a regular participant to co-host like one does in a meeting. I just see the "make panelist" option.

So me thinks we now have to add a license for each of our 4 helpers!!!! $$$$$$$$
