Mortar networking assign owner server has authority by default

Hey guy's I'm trying to create a mortar which only 1 client can control, these are my current codes.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Networking;
5.  
6. public class player : NetworkBehaviour
7. {
8.     public Transform mortar;
9.  
10.     public void Start()
11.     {
12.         mortar = GameObject.Find("Mortar").transform;
13.  
14.     }
15.  
16.     public void Update()
17.     {
18.         if (isLocalPlayer)
19.         {
20.             if (Input.GetKeyDown(KeyCode.E))
21.             {
22.                 Cmd_PressedE();
23.             }
24.         }
25.     }
26.  
27.     [Command]
28.     public void Cmd_PressedE()
29.     {
30.         mortar.GetComponent<mortar>().ChangeOwnership(connectionToClient);
31.     }
32. }
33.  

and my mortar script

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Networking;
5.  
6. public class mortar : NetworkBehaviour
7. {
8.     public void ChangeOwnership(NetworkConnection id)
9.     {
10.         this.GetComponent<NetworkIdentity>().AssignClientAuthority(id);
11.     }
12.  
13.     public void Update()
14.     {
15.         if (hasAuthority)
16.         {
17.             // runs on the client that has authority
18.             // runs on the server always
19.         }
20.     }
21. }
22.  

Now the issue I'm having is that the client that is hosting the server will always have 'hasAuthority' set to true by default, how do I make it so the server does not have authority by default?

 

Or do I have to do it this way?

Code (CSharp):

1. if (hasAuthority && this.GetComponent<NetworkIdentity>().clientAuthorityOwner != null)
2.         {
3.             Debug.Log("has authority");
4.             // runs on the client that has authority
5.             // runs on the server always
6.         }

though
this.GetComponent<NetworkIdentity>().clientAuthorityOwner is always null on client

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Networking;
5.  
6. public class mortar : NetworkBehaviour
7. {
8.     public void ChangeOwnership(NetworkConnection id)
9.     {
10.         this.GetComponent<NetworkIdentity>().AssignClientAuthority(id);
11.     }
12.  
13.     public void Update()
14.     {
15.         if (isServer && this.GetComponent<NetworkIdentity>().clientAuthorityOwner == null)
16.         {
17.             return;
18.         }
19.  
20.         if (isClient && !hasAuthority)
21.         {
22.             return;
23.         }
24.  
25.         Debug.LogError("has authority");
26.     }
27. }
28.  

This might work, kinda hacky way of doing it though I feel like
