openlayers : tile layer from v 5.3.0 to v 6.12.0

Question

I try to update this layer from ol v 5.3.0 to 6.12.0 and the error is "ReferenceError: TileLayer is not defined" as if the function was not loaded from the ol library call :

<link rel="stylesheet" type="text/css" href="/iliad/bibliotheques_javascript/olv6.12.0/css/ol.css">
    <script type="text/javascript" src="/iliad/bibliotheques_javascript/olv6.12.0/build/ol.js" data-url="/iliad/autoconfINRAP.json"></script>
    
    

the layer code en v5.3.0

var osmLyr = new ol.layer.Tile({
    olParams: {
        crossOrigin: "Anonymous",
    },
    source: new ol.source.OSM(),
    opacity: 1,
    name: 'Carte Osm',
    description: "carte open street map, https://www.openstreetmap.org"
});

and the v6.12.0 code

    var osmLyr = new TileLayer({
        source: new OSM(),
sourceParams: {
            crossOrigin: "Anonymous"
        },
        opacity: 1,
        name: 'Carte Osm',
        description: "carte open street map, https://www.openstreetmap.org"
  });
