Its possible convert this Script of a tool to a ImageButton right?

this is a script of a tool that can grow the size of a player, i want convert it to a image button, i can do this right? just converting the function of (MouseButton) to (OnClick) right?

bin = script.Parent
character=game.Players.LocalPlayer.Character
siting= false
function onButton1Down(mouse)
resizeImplementation(character, 1.42)
wait(0.03)
end
