Battle Royale spectator

Hi guys. Who knows how to make the spectator mode in the third person? How this is done on a server Battle Royale.

 

As I know, Rusts Spectate mode supports third-person.

 

I am pretty sure its via the PlayerFlags, I did play with it a little before but haven't got an example to hand

Code:

player.SetPlayerFlag(BasePlayer.PlayerFlags.ThirdPersonViewmode, true);

 

Strange ... The flag does not work if you are the admin, but if you're a player, is running.
