Add widget on RepNotify

An example of what I would like to achieve: replicate a door (opened/closed) and update the text on a widget (“opened”/”closed”). Using RepNotify, I know how to replicate the rotation of the door. But how can I request every player to add/update the widget right after? I need to get a reference to the local PC, right?

kinda depends on the UseCase but an event dispatcher might be a better idea.

But in the door actor BP, how can I reference the individual player controllers? How would I script it? I don’t know what to put in the RepNotify function, which, if I’m not mistaken, executes on the server and on all clients.

what kind of widget is it? for instance if it is a widget component on the Actor, if not how/where is it added to the screen?
