What email is in my Fortnite account?

I downloaded fortnite on the ps4 and was logged on directly without doing anything. I wanted to ask whose email I have in there because the email that is in my ps4 acc is not.

I know how to do it

How do we know now? We don't know you and can't know whose account that is

Go to epicgames.com and log in with your acc. On. Press Sign in with ps4 or something and enter your Ps4 data. The system will recognize that you are connected to an Epic games account. Then press general information and there's the email address somewhere above
