Is this the ultimate Make challenge?

I’ve been trying to build this scenario in Make for 2 months with no luck, and even Make support hasn’t been able to figure it out. I’m at a loss as to how to get this to work. I thought maybe someone on this forum can do it. Here’s the “challenge.” I want to have Google Calendar trigger ChatGPT to write a monthly newsletter that gets emailed to me for review/editing in a Google (pre-fill) Form, and then once I approve of the email, I click submit, and it gets emailed out to all of my subscribers in a Supabase email database. I believe this would have to be 2 scenarios. The first one is to create the newsletter and email it to me, and the second scenario is to send the newsletter to my subscribers. Any help would be greatly appreciated!
