Whats an alternative to get the players mouse?

I'm making an admin script but I need to press Z in order for it to work Just because I want to avoid message commands

but

local Mouse = game.Players.LocalPlayer:GetMouse()

only works in a localscript and my admin doesn't work as a local script anymore

so can someone either tell me how my script can work in a local without messing up the functions of my script?

Here's my script :

--Commands

--chat commands--
--Green
--Red
--Yellow
--Blue

--key commands--
--z    

local Admins = {"YouShalllNotPass", "Player", "Player1",  "Ray5069", "TacitaVolpes", "Wildfighter812", "LisforLucas"}
function IsAdmin(PlayerInstance)
 local PlayerName = PlayerInstance.Name:lower()
 for i = 1, #Admins do
  local AdminName = Admins[i]:lower()
  if AdminName == PlayerName then
   return true
  end
 end
 return false
end
game.Players.PlayerAdded:connect(function(NewPlayer)
repeat wait() until NewPlayer.Character

local Mouse = game.Players.LocalPlayer:GetMouse()

 if IsAdmin(NewPlayer) then
print'Ventivian Commands have been hooked into the system'

Put a script within the admin script, it must be disabled, but, it will say this:

local mouse = game.Players.LocalPlayer:GetMouse()
-- your part of the code here --

This would be your script:

local getscript = script.LocalScript:Clone()
getscript.Parent = AdminName
getscript.Disabled = false
