The Whereby app is part of Airtable Apps, a Pro plan feature. Apps let you extend the functionality of your bases: you can use apps to bring new information into Airtable, visualize and summarize your records in colorful ways, and even directly integrate your Airtable bases with your favorite apps.
To set up the app, you'll first need to sign up for free with Whereby and set up a room. Next, add a Whereby app to your base, and specify the appropriate URL for your Whereby room.
Once you've set up your Whereby app, you can click on the button inside the app to jump into the video chat.
If you're having trouble operating the Whereby room, you can look through Whereby's support library for further assistance.
