How I include other host into my meeting?

@Ascending333 were you looking to add them before or after the meeting starts?  If you want to add them before the meeting starts, you would need to add an alternative host.  Both you and the alternate host would need to be licensed.  

If you want to set someone up after the meeting starts, you can click on the dots by their name in the participant list and assign them co-host rights.  You need to have a licensed account to do this.
