Godot multiplayer not displaying up

Godot model

4.5 Steady

I am attempting to create a multiplayer recreation. Since that is my first multiplayer recreation, I began with a easy LAN setup.

The way it’s purported to work:
When host_button flame is pressed DBNetwork.init_server() and when join_button flame is pressed DBNetwork.init_client(). There’s additionally a host_and_join_button It tries to host the server and spawn in a participant. This triggers the host_player_exists variable.

Code:
DBNetwork.gd:

extends Node

var network_peer : ENetMultiplayerPeer
var DEFAULT_PORT : int = 43500
var LOCAL_IP : String = "localhost"
var MAX_CLIENTS : int = 10

func init_server() -> void:
    network_peer = ENetMultiplayerPeer.new()
    network_peer.create_server(DEFAULT_PORT, MAX_CLIENTS)
    multiplayer.multiplayer_peer = network_peer
    print("DBNetwork: Server Hosted Efficiently")

func init_client() -> void:
    network_peer = ENetMultiplayerPeer.new()
    network_peer.create_client(LOCAL_IP, DEFAULT_PORT)
    multiplayer.multiplayer_peer = network_peer
    print("DBNetwork: Consumer Created Efficiently")

MultiplayerSpawner.gd:

extends MultiplayerSpawner

@export var player_scene : String
@export var host_player_exists : bool = false

func _ready() -> void:
    multiplayer.peer_connected.join(spawn_player)

func spawn_player(id: int) -> void:
    if !multiplayer.is_server():
        return
    var participant : CharacterBody3D = load(player_scene).instantiate()
    if host_player_exists:
        participant.identify = str(id+1)
    else:
        participant.identify = str(id)
    get_node(spawn_path).call_deferred("add_child", participant)

func _on_host_and_join_button_pressed() -> void:
    if !host_player_exists:
        spawn_player(1)
        host_player_exists = true
    else:
        print("DystopianBots: Failed To Spawn Participant! (Host Participant Already Exists)")

Participant.gd:

extends CharacterBody3D

@export var SPEED : float = 100.0
@export var camera_sensv : float = 1.0

func _enter_tree() -> void:
    set_multiplayer_authority(int(identify))

func _ready() -> void:
    $playerNameLabel.set_text("Participant "+str(identify))

Tutorial I adopted:

Drawback:
Though the logic of my code is okay (in my view) and the tutorial I adopted was adopted accurately. The server hosts and the shopper joins efficiently (no debug errors), however the participant doesn’t seem.

How do I repair this?
