As the official documentation states, you can upload a source file to OSS and translate it, once in your bucket, to a SVF with the Model Derivative API.
But is it possible to skip the translation step, directly uploading a SVF project (for example, one of these: https://forge-rcdb.autodesk.io/gallery) and loading into the web viewer?
I haven't been able neither to do it nor find any documentation yet.
