[xela-zone]

Submission checklist

• I have searched existing issues and confirmed this is not a duplicate.
• I am using the latest available version of Noctalia and of the plugin.
• This is a bug in a community plugin, not in Noctalia itself (those belong in the noctalia repo).

Plugin

radimous/prismlauncher-instances

Plugin version

1.0.1

Bug description

when using noctlaia setting "Launch apps as systemd Services", prism insances do not launch as different instances, instead as part of the noctalia service.

Steps to reproduce

launch a instance using /pl
observe systemctl status --user noctalia

Expected behavior

it follows the noctalia setting for cgroups

Actual behavior

minecraft is launched as part of noictalia's CGroup

 CGroup: /user.slice/user-1000.slice/user@1000.service/app.slice/noctalia.service
