Switching between internal and discrete GPU (DRI_PRIME setting)

Hello, world!

Please help me out I tried to add DRI_PRIME=1 option to apps command in my Whisker menu (i use XFCE) Example: "DRI_PRIME=1 gimp"

But it gives me error like "failed to execute command no such file found"

When i run an app in terminal (same DRI_PRIME=1 gimp for instance) it works.

My distro is Linux Mint XFCE 21.2

Thanks to everyone in advance!
