Collab Viewer Bookmarks - teleporting everyone to this location

Hi everybody,
I’m currently building an education tool based on the Collab Viewer template (the archtecture version) in 5.3
I love the “bookmark” funtionality and ability to teleport to a pre-defined set of locations. What I need to accomplish is that I, as the teacher and host of the session, can teleport all other users (my students) to a bookmark at once by pressing a keyboard button. The learning journey will be build so that the students can freely explore the content but that I can also call them together in certain spots.
All participants will be in the same room wearing VR HMDs tethered to gaming PCs which run the experience.
I tried to understand the logic of the BP_Bookmark blueprint but didn’t find a way to apply the teleport to all players and not only the one who pressed the button.
Any help would be very appreciated!

Hi Again,
I managed to put together this solution in the Level Blueprint. It mostly works as I want it to. It teleports all players to the destination and only works if the button is pressed on the system hosting the CollabViewer session. The only thing that dos not work is the rotation. All players keep lookiing in the direction they looked before the teleport. Any ideas how to fix this?
