Google Calendar Sync

Hello, I have tried to follow your integration tutorial with Google Calendar, but it is impossible to connect, when I complete all the fields, I simply cannot access the calendar, it keeps loading and never ends, I sent an email requesting help and support almost 15 years ago days, but I never had an answer, is there a way to request a consultation with you to help me with this integration?, I cannot connect it, the sync button does not appear, not even the calendar activates the Google Calendar Sync :(`
