Why is there no "Ungroup Accessories" button in my Home app
In my Home app, I have grouped two lights successfully. Now I want to ungroup them, as per this article, https://www.trustedreviews.com/how-to/how-to-group-lights-in-homekit-4175104, there should be a "Ungroup Accessories" option:

Can anyone please let me know how to ungroup the lights now?
