Docusign Developer account verificationi issue

I am a developer/consultant setting up a DocuSign API integration for my client using Make.com. I have a question about the Go-Live verification process.

Here is my situation:
- I created a DocuSign Developer (Sandbox) account under my own name (Abdul Rehman) and my own email
- My client has an active DocuSign eSignature Standard production account under their business email (*****@*****.***)
- The production account admin is Edgar Samuel Cornejo Farias 
- I created an Integration Key in my developer account and submitted the Go-Live form
- During the Go-Live PowerForm verification process, it is asking for ID verification

My questions are:

1. Can I (Abdul Rehman) complete the ID verification as the Application Manager/Developer, while linking the integration key to my CLIENT's production account (Account ID: xxxx)? Or does the person verifying their ID need to be the admin of the production account?

2. If the Application Manager and the Production Account Owner are two different people, is that acceptable for Go-Live approval?

3. Will there be any issues or complications later when using the integration key in production if the developer account and production account belong to two different individuals?
