How should I do manual domain verification?

I would like to review a Zoom application and would like to ask you about domain certification.

I cannot click the Validate button unless the domain of the service and the domain of the Terms of Service and Privacy Policy are the same.

In this case I think I need to do manual domain verification.
Could you guide me on the procedure of manual domain verification?

Hello @zoom-app-public please refer to this post for information on Manual Domain Validation: Domain Validation Explanation
