how do i set a custom respawn button?

i have a main menu in my startergui that's scripted to spawn in as an elk (or any animal i have planned, but i only have the elk for now). it removes the player model, but when i reset the player doesn't respawn, the elk just perpetually stays there dead. so i wanted to script in a button for someone to press that respawns their player character, so they can click the button again and repeat the cycle.

here's my localscript, as you can see i have the userinputservice and my desired button defined at the top, i just can't find a way to get them to work, all the functions i wrote don't work

local MainMenu = script.Parent
local Player = game.Players.LocalPlayer
local PlayerModel = Player.Character
local uis = game:GetService("UserInputService")
local K = Enum.KeyCode.K
----------> BUTTONS
local ElkButton = MainMenu.MainFrame.SelHerbivores.Elk
----------> MODELS
local Elk = game.ReplicatedStorage.Animals.ElkMale.Adult
--------------------------------------------------------------------------------

ElkButton.MouseButton1Click:Connect(function(player)

    local SpawnElk = Elk:Clone()
    local OldModel = PlayerModel

    SpawnElk:SetPrimaryPartCFrame(OldModel.PrimaryPart.CFrame)

    Player.Character = SpawnElk
    SpawnElk.Parent = workspace

    PlayerModel:Remove()
    MainMenu:Remove()

end)

i tried stuff like

uis.InputBegan:Connect(function()
K = Elk:Remove()
K = Player:LoadCharacter()
end)

but that didn't work obviously
