Restore IDEA Touch Bar Settings or Set Touch Bar to F1, F2 When Using IDEA

I somehow set IDEA's touch bar to show F1, F2 function keys, but couldn't find the setting anywhere. Here's the solution.

Check Your IDEA Settings

According to this documentation: Touch bar support, restore the configuration in settings.

If this configuration doesn't exist, it means it's controlled by macOS system settings.

Check System Settings

Keyboard -> Touch Bar Settings

Keyboard -> Keyboard Shortcuts

Remove IDEA from the function keys list
