I want's to send invitation email's in Lumen.
Currently using: https://github.com/spatie/laravel-google-calendar
This package is in Lumen (Laravel micro framework).
I have completed all the Google API related steps given in this package. But still getting Google exception as
"message": "Service accounts cannot invite attendees without Domain-Wide Delegation of Authority."
Even though I have enabled domain wide delegation in service account.
Also had doubt, Is it compulsory to have gsuite account? I am just trying with my normal gmail account.
