You can set up your own video call green-screen backgrounds in the platform!
Visit your clinic settings → "Video calls" → "Upload new" to add new background images. You can also set a new default image, and delete existing images.
To add a background to your video call, click "Settings" on the lower-hand side of the screen when already in the call, and you will be able to choose among your uploaded background images that will be immediately applied once clicked on.
