Switch Host Leave then Start a New Meeting

I want to start a meeting then have 2 people join the meeting, a co-worker (who also has a paid zoom account) and a client. After meeting with both of them for a while, I want to give my co-worker host control. I will then drop off/leave the meeting, but my co-worker will continue to meet with the client for a while. As this is going on, I want to start another meeting with someone else. I tried doing this, but it wouldn't let me and told me that another meeting was in progress. How can I accomplish this?
