Using OWL-Livestreaming-Toolkit for Multiplayer

I set up an Environment in a Multiplayer VR-Game that includes a Plane which has a Material that shows the content of my second screen (“display 2”) via the OWL-Livestreaming-Toolkit.
How would I set up my Blueprints for it to show the same on all Clients and so that it doesn’t search for a “display 2” at all the clients’ PCs?
I played around a bit with the “Switch Has Authority”-Thing but i cant figure out how to replicate just the material that is created on my PC (Server) onto the Clients or how to create a Blueprint Actor that includes the plane and the material that does the same.
