Is onSend now support on Outlook desktop?

I am trying to create an Outlook add-in with the onSend function. I can see on the GitHub onSend Tutorial that onSend is only supported on Outlook web and 365. Has this been updated now (the readme is 2 years old)? I am trying to debug mine on Outlook desktop 2016 (using Visual Code + Edge extension) and the debugger never reaches the function I created and that is supposed to be reached during the onSend event.

If still not supported, can I still deploy this add-in via 365 (admin) and get it reflected on Outlook desktop 2016?

Thank you very much.
