Question Email address - how to delete it from the system


Good evening ! I received a call from someone who already has a gmail account connected. The problem is that when I install an application and I need to create an account, for example, I get several emails from which I should choose one or create an account with another new email. I would like to know how to delete all the emails that appear to me, it bothers me that they keep appearing there. Is it in settings somewhere or in chrome/google account where? Thank you in advance !
