How to open a door

That interface font choice breaks my brain.

I don't get it. I am trying to reverse push it with my palm but every time I move my hand back the door doesn't come with it.

But how do you make the eggs reassemble themselves?

I hope when I get dementia I won't forget that there is a youtube instruction video for everything. I just need to remember they exist. That's the one thing I must not forget.
