Contextmenu in Listbox when Cell is edit=true

Hi folks,
how can I use a Contextmenu in a Listbox Cell, when the Listbox-Cell is edit “TypeEditable = true”?
When the Cell is edit, I see only the Default Contextmenu from macOS not my menu.
Is the mode “TypeEditable=false”, I see my Contextmenu.


A little effort in searching this forum would have revealed someone who asked this exact question, along with an explanation, and a viable workaround.
