How do I put this answer in desmos?

I asked a question on math exchange. A user gave me an answer that I have no idea to put in desmos.

This is where my desmos problem is. I am trying to have a point orbit along a rotated ellipse path.

This is where someone responds to my question, but I have no idea how to put it in desmos.

To state my question again: How do I have a point along the rotated ellipse in my desmos graph?
