Displaying inlay hints "offUnlessPressed" in Visual Studio Code under Windows in Parallels

I am using the "offUnlessPressed" option for the inlay hints in Visual Studio Code, the inlay hints should then displayed via Ctrl-+Alt in Windows. But despite trying some keyboard shortcut settings in Parallels for the VM, I could not manage to show the inlay hints there (something just very shortly visible with certain settings). Has anyone achieved to use this feature under the described circumstances? Thanks.
