How to turn off auto adding apps to docker?

Since updating to A15, my FP4 now automatically adds apps to the docker if there’s a spare slot.

I don’t want that. How do I stop it? I can’t find any option for it.

Hello
I believe these are launchers settings.
Which launcher are you using?

In quickstep this would be home settings.

Edited to say you meant dock and I need a bit more time to find these with quickstep

Hi - all those settings are (and were) in the off position. I can’t find any others. The launcher is Quickstep.

Hi,
yes. I switched my launcher back to quickstep and spent some time trying to figure this out, but still have no clue. But at my phone they are not added automatically, I can have a dock half empty, still - unfortunately - no idea how to get there.
