How to remove add new button from within a form?

[sorin_mihai]

Hy,

I have a form (reference view) for adding new projects in a task management app.
In the form, when selecting the responsible person for the new project, there is a dropdown list with the names and pictures of the team. But there is also the possibility (action button) to add a new member of the team from here.

How can I make that button go away?
(or bonus - How can I make that button go away if the user is not admin?)

I want to remove it because I have a different form for adding new team members and I don’t want users to accidentally add new users when filling up the form for new projects.
( the app is not in english, but I hope that’s not an issue for helping me find the settings to remove the button )

Thank you
