Running CSDM with Steam in Firejail on Linux

[dgogovski]

I'm trying to get CSDM to work when Steam is running in Firejail. Tried looking at the source code for a bit but couldn't figure out which parts of steam/cs have to be accessible outside the sandbox for the app to work.

As far as I see, there are a couple possible approaches:

1. find out which parts of steam/cs have to be accessible outside the sandbox and add exclusions for them in the Steam firejail profile
2. start running CSDM inside the sandbox in which Steam is running (preferable but I'll have to look more into how this can be done)

Any ideas on how to get this to work are welcome.
