How to use Canvas Filter on leaflet map

[estamos]

Hi and congrats for your great work .

I would like to ask you how can I use Canvas Filter eg WaterTransparent on a simple leaflet map as mentioned in code below ?Note that I have already included the required Javascript file .
I am using leaflet v1.0.3 .

require('leaflet-tilefilter/master/src/leaflet-tilefilter.js');

const map = L.map('map', {
      center: [30, 25],
      zoom: 2,
      minZoom: 2,
      maxZoom: 4
    });

Thank you in advance .
