Keyboard Shortcuts don't work in VirtualBox

Describe the bug
I try to convert some shortcuts like Cmd+C (^C), Cmd+V (^V), Cmd+A (^A), Cmd+Q (Alt+F4), Cmd+W (^F4) to their equivalents inside a VirtualBox guest system that runs Windows 10, but they don't seem to be captured by VirtualBox. Tried to use the app name, path, etc. None of them works.

Same with Touch Bar.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Keyboard, Touch Bar

MacBook Pro 2016 13", iMac 2020
