Edit registration fields in wordpress admin?

Question

WordPress

Good day!
Site on Wordpress. User types are created using the Ultimate Member plugin.
The task is this: there are two types of users on the site - Partners and Clients.
Partners will have the right to create new users - Clients. That is, in the admin panel of Partners, 2 items are available: editing a profile and creating a new user.
Question: how to customize the "add a new user" form in the admin panel, that is, add a couple of additional ones there. fields? Or maybe there is a way to bring such a registration form to the front-end and customize it there?
Thank you!
