How to write a spatial filter?

[swdmike]

Sorry to bother, but could you please help me with writing a spatial filter, such as an intersect filter?
What is wrong with the filter?

var tipgUrl = 'http://ip/collections/showcase.test_202305/tiles/WebMercatorQuad/{z}/{x}/{y}?filter=INTERSECTS("Polygon ((...))")'
var tipgLayer = L.vectorGrid.protobuf(tipgUrl, {
vectorTileLayerStyles: {
'polygon': {
	fill: true,
	weight: 1,
	fillColor: '#06cccc',
	color: '#06cccc',
	fillOpacity: 0.2,
	opacity: 0.4,
}
}
});
tipgLayer.addTo(map);
