How do I get this damn thing off the wall? (more info in the post)

I didn’t find it "technical specifications"/composition of these markers, so I can only use the image/brand.

Listen, the youth showed me the wall. Since I didn’t paint the wall myself, I don’t know what kind of paint it is – I know that there is a thin layer of paint and there is probably no ground underneath it. The color of the egg/sponge shell.

I tried to treat the fresh marks very gently with a wet baby wipe. No dust. Then I tried the smooth side of a dish sponge with warm water and a little dish soap. No dust.

I only slightly blurred the traces and discovered that under the thin layer of the biscuit wall there was a hideous greenery, just like in our great-grandmothers’ houses.

Please help, it looks hideous and I don’t want to paint the entire wall. I will be grateful for all suggestions, especially from people who understand the topic chemically.
