Is it possible to add a button into the scene?

That would certainly not be bad, but I can’t afford that at the moment. See the Discussion about this side link at the bottom of * discourse.threejs.hofk.de

It also takes time to read, especially since my English is still poor and I use a translator:2020-03-20 19.52.23

But maybe someone who has already done such a thing would like to add it? Then please contact me.
