mySplineViewer.addEventListener('load-start', (e) => {
	console.log('loading started', e.detail.url);
});

Exporting for <spline-viewer from Spline editor

If you want a scene to be loaded by the <spline-viewer> component, you need to export it from Spline editor using the Spline Viewer export type. First click on the Export button from the toolbar, then click on the Spline Viewer tab on the sidebar of the export modal. Finally click on update and when export is done you can copy paste the code snippet or the exported URL.

Listening for events outside of the canvas
