Normally the shortcut is "⌘⇧/".
But being that "/" is on the "7" key on a Danish keyboard, this shortcut now opens the Help menu - ironically.
Manually adding it as a key binding does not help.
As far as I remember, the exact same thing happened last year with Xcode 13.
Using a french AZERTY keyboard I was able to fix it by going to:
System Preferences > Keyboard > Shortcuts tab > App Shortcuts > Uncheck Show help Menu
in App Shortcuts
You'll still need to Manually add it as a key binding
