Need Apple calendar events to show on Google calendar

Hello,

I have searched for the answer to this question but the answers I saw didn’t work for my situation.

Eventbrite used to have a link on the event details page of their website that added the event to Google calendar. Worked perfectly until they removed it 😡. The link now exists on their iPhone/iPad app and adds events to the Apple calendar under the Eventbrite calendar. I need to get those events to my Google calendar to displayed on my website. Once on the Google calendar I need to be able to edit the event and change the calendar assignment from Eventbrite to 1 of the 8 calendars on Google calendar.
