Form Fragment for Assignee Field – User Picker instead of Text Input?

Hi,

I have an object definition with an Assignee field. When I generate a form container for it, the field gets mapped to a Text Input fragment. What I actually need is a proper user picker, like the one in the auto-generated Object Entry edit form when a Panel Link is configured for the Object Definition.

Is there a built-in or community fragment that supports the Assignee field type as a user picker? Or any recommended workaround?

Thanks!
