UMG: click on mesh in game = camera moves

i have a question.
i have a UMG menu widget from which the user can control some things. i want to make a system, in which the user can click on a door in the game from the widget, and then the camera moves to the door. some kind of point and click, but without a moving charakter. there are only just mousecontrolled camera movements.

i know how to click on a button to change the camera, but how can i make the camera swich by click on game objects?

any ideas?
thanks. =)

push can someone help here?
