How would i make a contextactionservice act as the button "R"?

Im trying to make a contextactionservice replace the button "R". So far i have, local player = game.Players.LocalPlayer local cas = game:GetService("ContextActionService") halp pls

If you want to make when a player presses R then you can use UserInputService, a more understanding way to register button keys

so here

local UIS=game:GetService("UserInputService")

UIS.InputBegan:connect(function(bttn)
	if bttn.KeyCode==Enum.KeyCode.R then
		print("The Key R was pressed")
	end
end)
