Which handle gets granted access to Twitter Card Analytics?


I’m filling out a domain approval request as the last step in implementing Twitter Cards for my client’s website, and I’m just wondering if the contact listed as the “Administrative Contact” will receive automatic access to the site’s Twitter Card Analytics? The account itself is managed directly by my client, and I would like for them to have direct access to Twitter cards. So should I be listing my client’s Twitter handle or my own as the “Administrative Contact” on the approval request?

Any information is GREATLY appreciated, thank you so much!
