Mapbox Layer on Mapping Module Overlay

Hello,
My team and I would like to add a QDS overlay over a map in the Mapping module (v1.5.0) on Omeka S 3.2.1.
We have created the overlay here on Mapbox: https://api.mapbox.com/styles/v1/nlinden/cl9ya59k9004r14lng036ullh/wmts?access_token=pk.eyJ1IjoibmxpbmRlbiIsImEiOiJjbDl5YjdvNXIwMnRmM29sbmNpb3hqNDM0In0.s06rSxqvrJrcbi_SPmQN4A

We have then tried to put into the WMS overlay module with the URL
and adding the name of the layer (title) QDS_Test. But nothing is coming up. We are not sure if this is possible at all, and if it is just a matter of selecting the right Layer/Style or something with our link that would need to be tweaked.

Many thanks,
Sanjin
