Meeting starting at 7 and one ending at 7

Hello Zoom Community,
I am trying to manage two meetings on the same Zoom account and I am looking for guidance on the best setup.

I currently host:
 Advice 6:00 PM
Study 7:00 PM

There may be times when the first meeting runs over while participants are beginning to join the second meeting. My account is licensed, but I do not appear to have access to concurrent meetings.

I would like to know:
What is the best way to allow the 7:00 PM meeting to begin if I am still in the 6:00 PM meeting?

Can an alternative host fully start and manage the second meeting without me present?
If I enable “Join Before Host,” will participants be able to communicate with each other before I arrive?
Are there any recommended settings or workarounds for churches or organizations running back-to-back meetings from one account?
Thank you in advance for any help or recommendations.
