Assign authority to server when Local Player Authority set true

Hi! How we can set Authority to server, when "Local Player Authority == true"?

i mean:

We set "Local Player Authority" to true, for cars objects. When we spawn car, on server hasAuthority == false
When user inter Car, we make AssignClientAuthority(playerInCar) - on server hasAuthority == false
When player leave car, we do - RemoveClientAuthority(playerInCar) and now - on server hasAuthority == true

how we can make hasAuthority == true on server, after spawn?

 

You would set local player authority to false and spawn with NetworkServer.Spawn. When the object spawns, the server should have authority.

 

if do so, when i try use AssignClientAuthority - unity say local player authority must be true
