Wix Code Form Notifications Assistance

I set up the event handler, sendgrid, and page code - but still not getting notifications.

There appears to be no errors in my code. Can someone from the CODE team take a look?;;

Have you followed the instructions here ?
Have you generated your own API SendGrid key?

Yes - I have, but still not working.
