Auto fill name, email and other fields for registered users

Hello,

I have a contact form with Ninja Forms, however, it shows the same to registered usrs and non-registered users.

Is it possbile to autofill username, email, etc for registered users. Or just completely hide these fields for registered users and just show you are logged in as this username. and when email goes to the admin, it shows the name, email, etc for the user that sent the email.

I’d appreciate your kind support.
regards
