FPS FOV change in real time for both players

Hello, I would like to change FOV in runtime in FPS character for both players at the same time.
I have this setup (replicatged DEV FOV integer )but it works only for each player. How can both players (listen server and client) change each others FOV? I want them to access each others FOV.
Thank you for any help, or is there a better way to set up FOV values than an switch on INT?

Use a timeline if you want it to be more like a zoom in effect than a sudden change to an fov,

Youll have to use an interface or event dispatcher or basically anything else that you can get a reference to the other players character/controller and then just have a custom event that changes fov with the timer

It looks like your FOV is just (90 - 10*DEV FOV)

Edit: This means you can omit the switch and simply use the the result of the little calculation
