Zoom App Approval: Stuck on Domain Verification for AWS Lambda API

I'm facing an issue during the final setup of my Zoom app approval process. I'm being prompted to verify an AWS Lambda API domain that I'm using in my webhook URL.

I control this AWS Lambda API domain but haven't verified it because it belongs to AWS. I'm unsure how to proceed and would appreciate any guidance or solutions.

Here's a breakdown of my situation:

Verified domain: My website domain is already verified.
Unverified domain: The AWS Lambda API domain is unverified.
Webhook URL: I'm using the AWS Lambda API domain in my webhook URL.

Any help or suggestions would be greatly appreciated. Thank you!
