Running c8y-remote-access-plugin --init on a system which is using a non-standard user (e.g. anything other than "tedge") causes the following error.

c8y-remote-access-plugin --config-dir /opt/homebrew/etc/tedge --init

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value:   × Failed to initialize c8y-remote-access-plugin. You have to run the command
  │ with sudo.

', crates/core/tedge/src/main.rs:50:58

Describe the solution you'd like

If tedge init --user myuser --group mygroup can be run with a custom user, then c8y-remote-access-plugin --init should also not have a problem with it.

It might make sense just to create the file using the permissions of the user running it, and ensure it is set to 644 so it can be read by other users.

Describe alternatives you've considered
