New static content type

Good day.

I cannot load any *.gltf files (part of 3D visualisation), permanent 404 error. Can somebody tell me necessary steps to register this type of files?

Thank you in advance,
Serge

Ok, found solution.

This code should be added to UseNopStatisFiles:

 var options = new StaticFileOptions
            {
                ContentTypeProvider = new FileExtensionContentTypeProvider()
            };

            ((FileExtensionContentTypeProvider)options.ContentTypeProvider).Mappings.Add(
                new KeyValuePair<string, string>(".gltf", "model/gltf+json"));

            application.UseStaticFiles(options);
