merge with view

Hello guys,
Merge isn't work on view; anyone know why?
I mean, merge could be performed in many way, but essentially is:
  • join sets
  • if matched update or delete
  • if not matched insert
it doesn't seem to be relevant if set is a table or a view.

Moreover also "insert + on conflict" doesn't work with view (in my case is a view on a single table with an instead of trigger)

There is a way to workaround to this issue?
