Thank you so much for opening this PR @svozza!

I have done a first quick review and it's looking good, only left a couple minor comments.

On Monday I will do a more comprehensive review with a test build of the utility and get back to you.

I'm not looking at the TS part because you guys are more expert than me in that area, but looking at the events it looks pretty good to me. I just made an observation because AppSync sends domainName when invoking with a custom domain name and when not invoking it is None.

Nice work and attention to detail @svozza! 👏
