[NOOB] Disable GameObject for every other client except local

Hi!
I have Player Prefab and Player Camera as separate GameObjects. So first I spawn Player Prefab and disable components if the client is not localPlayer with this code:

if (!isLocalPlayer)
{
for (int i = 0; i < componentsToDisable.Length; i++)
{
componentsToDisable.enabled = false;

}

}

this works fine exactly as intended, so now from one of the Player Prefab scripts i call a function to instantiate Player Camera now here's my problem how do I set this camera to have local authority and disable all of its components if its not local.

I tried putting Network Identity on Camera and checking "Local Player Authority". On the script then i tried to Check and disable components the same way as on Player Prefab

if (!isLocalPlayer)
{
for (int i = 0; i < componentsToDisable.Length; i++)
{
componentsToDisable.enabled = false;

}

}

but it doesn't work (it does not recognize this Gameobject as localPlayer)
