How to know if a user attempted to use Menu>Respawn?

I have a friend who wants to block Menu Respawning and also alert the user that your requested respawn has been rejected, and the game controls respawning only.

I have the script working great, renaming Humanoid to humanoid, and loading custom Health and Animations to fix re spawning and animation with the new humanoid name, but if I try adding another Humanoid to the character and do a Menu Respawn, it kills the character.

Is there a way to prevent killing the player, and being able to know if the player attempted to manually respawn?

coroutine.resume(coroutine.create(function()
    chr:WaitForChild("Humanoid")
    chr.Humanoid.Name="humanoid"
    while chr:findFirstChild("Health") == nil and wait() do end 
    chr.Health:Destroy()
    while chr:findFirstChild("Animate") == nil and wait() do end 
    chr.Animate:Destroy()
    local rep=script.Health:Clone()
    rep.Parent=chr
    rep.Disabled=false
    local rep=script.Animate:Clone()
    rep.Parent=chr
    rep.Disabled=false
    for a,obj in pairs(chr:children()) do 
        if obj:IsA("CharacterMesh") and obj.Name:find("3.0") then 
            obj:Destroy() 
        end 
    end 
    local hum=Instance.new("Humanoid",chr)
    while wait() do
        if hum.Health==0 then
            print("DENIED")
            hum.Health=100
        end
    end 
end))
