[Request]: GameScope force-grab-cursor argument

[ElecTwix]

Tell us the problem or your need

In Starcitizen I when I press F ( Interact Key ) it needs to display the mouse but because of Gamescope it doesn't I need to add --force-grab-cursor as a game scope argument but I couldn't add

Describe the solution you'd like

We could go with two options.

1. We could add --force-grab-cursor option to menu

Other solutions?

2. We could add a manual field like ENV to add arguments manually.
