based on the openlayers example at https://openlayers.org/en/latest/examples/wmts-layer-from-capabilities.html?q=wmts

i'm trying to load a WMTS in my own example here https://codepen.io/vishnu4/pen/EMBZdp?editors=1010 , but it really only seems to show just 1 large image that i can't zoom into to see more details. if i load it in QGIS, there are all sorts of other features that i'm not seeing.

How do i zoom into this WMTS to show the QGIS level of detail instead?
