How do I save my game menu (C #) [closed]

Hello, I'm having a problem when saving settings in the menu of my game, the resolutions and quality when pressing the save button, it saves. the problem is that I made a button that opens a panel with 2 other buttons, so that's fine. these buttons define whether the game is in "Portuguese" or "English", but I do not know how to save this change in my script, because the "Menu" script relates to the "Menu Pause" script or basically needs in a way that will save the change there, other things like resolution, quality, audio save right.
