How does host let someone back into a meeting that has been removed by Host

Hi Paul! To enable allowing removed participants to rejoin meetings for your own use:

1. Sign in to the Zoom web portal.
2. In the navigation menu, click Settings.
3. Click the Meeting tab.
4. Under In-Meeting (Basic), verify that Allow removed participants to rejoin is enabled.
   Note: If the option is grayed out, it has been locked at either the group or account level, and you will need to contact your Zoom administrator.
