How to add more field in domain.com/forum/users/user/edit/

Hi guys

I was trying to have some more custom user fields in https://www.domain.com/forum/users/user/edit/.

I could see that I can add more fields using form-user-edit.php – however, they are not getting saved on submit.

That means, I need to add the new variables in some other file in order to get them saved.

Can anyone help ?
Best.
