Show Sims 4 Walls ps4?

I'm completely desperate. I have been trying to make my walls in the house visible for over 1 hour but I just can't find it. I also google the whole time but the explanations all make no sense. Can someone finally help me, please?

On a computer there's the bar at the top, a room like this is shown there. If you click on it there are 3 settings for the walls. You can see the mark in the photo. If you're playing on a PS, I don't know exactly how that is.

Thanks but play on a ps4 and unfortunately there's no such symbol.

I just searched the internet again. If you press the "arrow" on the control pad (i.e. These arrow keys on the left side), which points to the left… And on the left side is…, these 3 wall settings should "switch" through. So there's the wall setting that all walls are gone, only a few important walls are displayed and all walls are there.

Maybe that will help
