How to close access to the administrator (creator of the account) in Google Adwords?

Question

Google

Hello!
Our administrator created a Google Adwords account for us. I linked it to my mail, and added our mail with the administrator role. It is currently not running an advertising campaign in GA and we plan to disable it by deleting the user in GA's "Account Access" section.
Tell me, please, will he still have the opportunity, as the creator, to restore access to the GA account in the future?

Answer 1

I checked how it works on my account.
Added another admin user.
I went under it, deleted the original one.
The original immediately lost access.
I did not find how to return it.
Well, maybe there are ways, but it certainly won't be easy.
Something like filing a complaint with Google. Or through the courts.
