How to use Fancybox 5 to show a photo when clicking a Leaflet marker

Question

Is this possible at all? This is my code so far

var marker = L.geoJSON(geojsonFeatureCamera, {
              pointToLayer: function (feature, latlng) {
               return L.circleMarker(latlng, geojsonMarkerOptionsCamera);
              },
              onEachFeature: function(feature, layer) {
               layer.on('mouseover', function(e) {
                do_something();
               });
              }
             });

I am able to do_something. E.g. open een Popup or write something to console. But I would like to open an image (of which the name is in feature.image) with FancyBox 5. And I am totally stuck on how to do that. Can somebody help me with this?

Thanks in advance!
