[Feature Request] Add mute/unmute/change volume action(s)

[login0false]

As the title says, please add audio actions that mute/unmute the app and/or change its volume. Some games don't mute themselves when out of focus (and lack such option), so I'd like to be able band-aid that myself without having to mute them manually (ugh).

Currently, this is doable through custom script if you use the svcl.exe from https://www.nirsoft.net/utils/sound_volume_command_line.html.

One thing that is kind of annoying is there is no way to pass the dynamic application name / executable name to the script, which means you may need to create a dedicated profile with different argument for each game you want to mute. (Alternatively, if you do not ever play multiple games at once, you can try to mute/unmute all the games together in a single script)
