Always display keyboard hints

Is it possible to always display keyboard hints in Gnome? These underlines are displayed when holding Alt.

Already tried:

  • Gnome Settings
  • Zorin Appearance
  • Gnome extensions
  • dconf-editor show-keyboard-shortcuts true

See underlined letters in screenshot for reference.

This function, which once existed and where keyboard hints were always displayed, seems to have been abolished in Gnome. Only in KDE Plasma it is still available.
