How to make procedures apply in another dimension?

I was trying out an idea of making a boss that teleports you into a custom dimension when you defeat it, beginning phase 2. However it doesnt seem to work, and all procedures that are supposed to apply onto the player after teleporting into the dimension is instead applied in the overworld. I also can't seem to make the block "Do _____ in server-side world" work, as it always returns a compilation error. Please help.

I have provided images of my procedures, and went into further depth in this reddit post:
