Openlayers - export url GetLegendGraphic for wms layers

[andreaordonselli]

Is it possible to integrate qgis2web to extract the url of the GetLegendGraphic in wms layer ?

In QGIS each wms layer has the url referring to the legend, called GetLegendGraphic

I would like the export of a wms layer to write this url after the title, as it happens for the standard layers
Example with url entered manually:

var lyr_ParchiNazionalidellaSardegnadatiindicativi = new ol.layer.Tile({
  source: new ol.source.TileWMS({
    url: "http://webgis.regione.sardegna.it/geoserver/ows",
    attributions: " ",
    params: {
      LAYERS: "dbu:PARCHINAZIONALI",
      TILED: "true",
      VERSION: "1.3.0"
    }
  }),
  title: "Parchi Nazionali della Sardegna (dati indicativi)<br />\
<img src='https://wms.cartografia.agenziaentrate.gov.it/inspire/wms/ows01.php?language=ita&version=1.3.0&service=WMS&request=GetLegendGraphic&sld_version=1.1.0&layer=strade&format=image/png&STYLE=default&'>",					
  opacity: 1.0
});
wms_layers.push([lyr_ParchiNazionalidellaSardegnadatiindicativi, 1]);
