Google recently added a widget to Gmail that lets users easily access a Google video chat (a.k.a. a Google Meet). Unfortunately, this can hide your labels and your Keeping Toolbar, especially if you are on a "short" screen. Here's how to remove the Google Meet widget from Gmail.
Update May 29, 2020: Google is rolling out the new settings to hide the Google Meet widget slowly across the globe. If you don't see the option yet, just check back in a day or so.

Google has added a new option in your main Gmail settings to hide the Google Meet widget. This is rolling out slowly across every Gmail account, but many users should be able to access it now.
1. Click on the "gear" icon in the upper right of your Gmail.
2. Navigate to the last item in the settings, labeled "Chat and Meet"
3. For the "Meet" option, choose "Hide the Meet section in the main menu"
4. Click Save and you are done!
