Copyright risk if a programmer uploads an application to the AppStore under a corporate account, but using personal email?

Question

Mobile development

I am the lead iOS developer. The customer is meticulous about registering copyright for the code. Does the customer bear any risks if I do not use his corporate mail when authorizing in AppleID?
If:
1. My personal developer AppleID is already in a corporate account, and it is the corporate account that uploads the application executable file
2. The customer's corporate account is displayed everywhere
3. Apple itself does not regulate authorship depending on the account, but it obliges you to fill in the Copyright field when publishing the application
4 I am dealing with issuing keys from a corporate account with which I sign the application, and also have access to the description of the application in the AppStore and product testing in iTunes Connect
I would like to hear arguments both from the point of view of our Russian legislation and as in other jurisdictions: the USA, Europe, South America.
Using corporate AppleIDs introduces significant difficulties in development, and for example, on Android, working with the Google Developer Console is impossible without Gmail mail. I also interviewed iOS developers from Yandex, Mail.Ru, Avito, Alfa-Bank, Sberbank, Tinkoff Bank - all of them do not oblige developers to use corporate mail for AppleID. But in my case, the experience of larger companies is not an argument.

You were correctly answered above, copyright and e-mail address (in your case, this is your personal data) are not legally related in any way. The presence of an email does not indicate authorship, does not provide rights to the work, it is the contact information of the person who placed the application in the appstore...
For example, an authorized representative (by proxy) can publish the application, indicating his contact information, and this will not mean that the authorized representative is the author ... the same is true for an employee of an employer performing an official task, however, such an employee must act on behalf of the employer and indicate work contact information, otherwise, in the event of a disagreement between the employer and the employee, it may be difficult for the latter to prove that he acted precisely within the framework of an official assignment, and not in his personal interests.
You are more likely to be at risk because you, as a non-author, have published someone else's application from your personal account ... do you have the right to publish?

Disclaimer: I'm not a lawyer and I could be wrong.
Gag: Copyright belongs to the author. Even his employer does not have copyright, but only exclusive rights to the result of copyright work - intellectual property.
You, as an employee, having written a program, have copyright on it, but you cannot dispose of intellectual property, since you completely transfer it to the employer.
As a publisher, you can publish software from your email.
If you quit, such actions on your part will be illegal.
I don't see where the problem is with the client.
