How can I hide the h1 header that says “Excalidraw Data” and everything below it?

What I’m trying to do

I like using Excalidraw in my notes, but the fact that the Excalidraw data appears below bothers me. It disrupts the ease of use. Is it possible to hide it using CSS code?

Things I have tried

Since I don’t know how to code myself, I couldn’t try much. I tried things I found here and there on the internet through trial and error, but none of them worked properly.

Link the parts you want from your ExCal files to your md notes.
Use Copy [[link]] for selected element(s)

You can hide the text under the heading by folding the heading. To do that, hover your pointer before the heading and click the arrowhead that appears. On mobile you can’t hover, but tapping that same spot will do it. Obsidian will keep it folded (except occasionally certain things make headings unfold, so you’ll have to refold it then).
