How to use template url generated from "Leaflet Title layer" app in an independent leaflet map?

I generated template url for my title using “leaflet title layer” app. It is ‘{z}/{x}/{y}?token=…’. My question is, how to add this title layer into a separate leaflet map that is totally separate from DD? I’ve tried below:

L.tileLayer('{z}/{x}/{y}?token=.....', {
	maxZoom: 18,

But it failed and showed “Failed to load resource: the server responded with a status of 404 (Not Found)” thx!
