Add/Remove slide group headers

How do I add/remove slide group headers? Shown in picture as Warm-Up, Activity 1, Cool-Down, etc. I cannot find anywhere in the activity builder to change this feature. Thanks!

You can edit them using the title on the slide or the </> button next to teacher tips. It depends on where the information was input.

Sadly, I looked in both places and there is nothing there.

I think these are a hidden feature that only Desmos and certain other activity creators have access to. Unless something has changed, I don’t think these can be created or edited by regular users.
