[Bug] Prime-run (aka command to force gpu offloading) does not launch engine

[Sans2280448]

FunkHub version

v.0.1.1

Operating system

Linux

Steps to reproduce

1. Open a desired mod executable, or engine
2. Change the Launch override to Native and a command to run "prime-run" or absolute path "/usr/bin/prime-run"
3. Launch the said engine. And get an error

Expected behavior

1. Open a desired mod executable, or engine
2. Change the Launch override to Native and a command to run "prime-run" or absolute path "/usr/bin/prime-run"
3. Launch the said engine.
4. The engine opens with dgpu offloading

Actual behavior

It just can`t run engines with the prime-run enabled. This is sometimes necessary to use, hybrid nvidia laptops use such setup on linux and use prime-run when needed to run some heavy-loaded applications such as games.

Do note that not all engines support this, notably some psych engine based mods just dont work with this option enabled.

Engine and version

any

basically shows, that v-slice works with this option on, but funkhub flatout refuses to run with it
