  It is either a string which may contain the following flags that will be replaced:

  or a callback function that's called with the following parameters z,y,x,quadkey and needs to return the url for the respective tile. The callback function needs to handle custom parameters by its own.

  example

  // string
  url: 'https://xyz.api.here.com/tiles/osmbase/512/all/{z}/{x}/{y}.mvt?access_token=YOUR_ACCESS_TOKEN'
  
  // callback function
  url: (z, y, x, quadkey) => {
      return `https://xyz.api.here.com/tiles/osmbase/512/all/${z}/${x}/${y}.mvt?access_token=YOUR_ACCESS_TOKEN`
