Then why I can't find it even with your keywords?

The other possibility is that it's not present for me because it might not be compatible with GrapheneOS?

But I have problems with search even for other apps. I'm OK with it it because FDroid is very good otherwise.

It shows up for me on GrapheneOS. I don't think the F-Droid search is OS-dependent anyways besides maybe the major Android version number. As the GP noted, for some reason the name is listed with the "3D Theme" addendum in the app which is a little bizarre. Does your browser support opening the link in an app, i.e. F-Droid?
