Being Developer to multiple AppStore Connect Account?

Hi All

I have my own main account associated with my Appstore connect account where I submit my own app.

I am now going to be working on another project, the AppStore account belongs to a client. Can it be possible to assign my email address as a developer/ admin to that account as well?

This way my email address will be associated with my account as well as my client's account?

Therefore when I perform a submit on my client's account for either the Appstore or test flight, would the security code be sent to my apple device or theres?
