Ok so for everyone that is using krz_personalmenu you’ll need to open the client/main.lua file.
Go around line 78 and copy and paste this line of code:

RMenu.Add('personal', 'components', RageUI.CreateSubMenu(RMenu.Get('rageui', 'personal'), 'Smonta componenti', 'Smonta componenti', 0, 0))

After you’ve copied this line, go around line 1078-1080 and copy & paste this code:

if RageUI.Visible(RMenu.Get('personal', 'components')) then
	RenderComponentsMenu()
end

Then last, but not least, step, go everywhere you want, outside of every function, and copy and paste this function:

function RenderComponentsMenu()
	local isArmored = false
	local playerArmour = GetPedArmour(GetPlayerPed(-1))
	if playerArmour > 0 then 
		isArmored = true 
	end
	RageUI.DrawContent({header = true, instructionalButton = true}, function()
		if isArmored then
			RageUI.Button('Smonta corazza (' .. playerArmour .. ')', "", {}, true, function(Hovered, Active, Selected)
				if (Selected) then
					TriggerServerEvent('atlantis_kevlar:armourRemove', playerArmour)
					RageUI.CloseAll()
				end
			end)
		end
	end)
end

After you’ve done that, restart the menu and you’re ready to go!
