Run as a specific user/group ?

Got the app up and running, works great (THANK YOU!)

However, it runs as administrator (I'm on QNAP for reference).

I tried adding UID and GID environment variables to assign IDs, but it doesn't work.
Is there anyway to have files saved as a specific user? That way Plex (hosted on another system) can delete files when I'm done watching them.

No source files, tests, or entry points are named. Start by locating the application's runtime and environment-variable configuration, then verify the requested behavior by checking that downloaded files are owned by the configured user and group and remain usable by Plex.
