As a general comment, something I would recommend is setting out some meeting etiquette ahead of time. Things like being on mute unless you are speaking. I'd also recommend learning the moderator controls, particularly how to mute individuals or mute all, how to record, how to screen share etc.
There is usually someone who won't and will typing loudly, eating their dinner, talking to someone etc. and you want to be able to silence them if you need to for the benefit of the wider call. In zoom, if you bring up the participants list, you can identify the guilty party or parties by looking at the microphone icon by each person as it indicates when noise is coming from that mic. If you put your mouse pointer over an individual's name as the moderator, you should have the option to mute them. Also, the "more" menu at the bottom of the Participants list gives you the option to automatically mute everyone on entry (I'd recommend doing this by default).
I'd suggest running a dummy meeting ahead of time and play around with the functions you think you will need. Tools like Zoom can also record the call so those who can't make it for whatever reason can still learn from it after the fact.
