Detect right click on prefab?

[FurryEskimo]

Hello.  I'm working on an improvement to some of my own code, but need a way to detect when a player has right clicked on their own follower.  I think this code is very similar to what I need, but I don't really understand it..  Could anyone offer some advice so I can make my own version?  This code appears to be a 'sit' command (which is cool), but I needed something simpler, a simple way to check if the follower's leader right clicked on them.

local SITCOMMAND = GLOBAL.Action(4, true, true, 10,	false, false, nil)
local SITCOMMAND_CANCEL = GLOBAL.Action(4, true, true, 10, false, false, nil)
	
AddComponentPostInit("talker", function(self)
	local old_Say = self.Say
	function self:Say(script, ...)
		if self.inst.prefab == "saberlion" then
			if script and type(script) == "string" then
				script = script:match("^%$%$(.*)$") or "GAO GAO GAO!"
			end
		end
		return old_Say(self, script, ...)
	end
end)

AddReplicableComponent("followersitcommand")

SITCOMMAND.id = "SITCOMMAND"
SITCOMMAND.str = "Order to Stay"
SITCOMMAND.fn = function(act)
	local targ = act.target
	if targ and targ.components.followersitcommand then
		act.doer.components.locomotor:Stop()
		act.doer.components.talker:Say("Sit!")
		targ.components.followersitcommand:SetStaying(true)
		targ.components.followersitcommand:RememberSitPos("currentstaylocation", GLOBAL.Point(targ.Transform:GetWorldPosition())) 
		return true
	end
end
AddAction(SITCOMMAND)

SITCOMMAND_CANCEL.id = "SITCOMMAND_CANCEL"
SITCOMMAND_CANCEL.str = "Order to Follow"
SITCOMMAND_CANCEL.fn = function(act)
	local targ = act.target
	if targ and targ.components.followersitcommand then
		act.doer.components.locomotor:Stop()
		act.doer.components.talker:Say("Come!")
		targ.components.followersitcommand:SetStaying(false)
		return true
	end
end
AddAction(SITCOMMAND_CANCEL)

AddComponentAction("SCENE", "followersitcommand", function(inst, doer, actions, rightclick)
	if rightclick and inst.replica.followersitcommand then
		if not inst.replica.followersitcommand:IsCurrentlyStaying() then
			table.insert(actions, GLOBAL.ACTIONS.SITCOMMAND)
		else
			table.insert(actions, GLOBAL.ACTIONS.SITCOMMAND_CANCEL)
		end
	end
end)
