How do I clear character appearance and set the same avatar for all players in my game?

Here is the script I did, but it's not working and isn't changing the avatar, but is clearing the appearance.

game.Players.LocalPlayer.Character.ChildRemoved:connect(function(child)
  print(child.ClassName, 'removed from character')
end)



game.Players.LocalPlayer:ClearCharacterAppearance()
--> BodyColors removed from character
--> ShirtGraphic removed from character
--> Shirt removed from character
--> Pants removed from character
--> CharacterMesh removed from character
--> Hat removed from character
--> Shirt removed from character

local player = game:GetService("Players").LocalPlayer -- Gets the clients player

player.CharacterAppearanceLoaded:Connect(function() -- Fires when all assets on character is loaded
    game.Players.LocalPlayer:ClearCharacterAppearance() -- Clears Appearance
    for _,BodyPart in pairs(player.Character:GetChildren()) do -- Loops through the characters body
        if BodyPart:IsA("BasePart") then -- Checks if the BodyPart variable is an actual part
            BodyPart.BrickColor = BrickColor.new("Black") -- Changes the body part to Bright Yellow
        end
    end
end)
game.Players.PlayerAdded:connect(function(player) -- Hat adder
    repeat wait()until player.Character
    local hatId = 168167370 -- Find the ID of the hat
    local hat = game:service("InsertService"):LoadAsset(hatId):GetChildren()[1]
    hat.Parent = player.Character
end)

game.Workspace.ChildAdded:connect(function(plr) --Pants and body adder
    local name = plr.Name
    local playerinplayers = game.Players:FindFirstChild(plr.Name)
     playerinplayers.CanLoadCharacterAppearance = false
     plr.Head.face.Texture = "rbxassetid://173789498" --Find an ID of a decal for your face.
     local shirt = Instance.new("Shirt", plr)
     shirt.ShirtTemplate = "rbxassetid://295960485" -- Find the ID of the shirt
    local pants = Instance.new("Pants", plr)
    pants.PantsTemplate = "rbxassetid://128946130" -- Find the ID of the pants
end)

game.Players.PlayerAdded:connect(function(player)
    local appearanceOverride = game.Players:FindFirstChild(player.Name)
    appearanceOverride.CanLoadCharacterAppearance = false
end)
