I found it independently, and wonder if this information could also be used to make the app work with lineageos as well.
I also did a cursory search of e/os search code for camera and include this merge to /e/os which seems especially interesting, since there is a service under a subdirectory called lineageos. I don’t feel too confident myself to go much further into the matter, though.
If anyone is in the lineages community and is confident enough in development to make a pull request, it would be really cool!
