I want to use Autodesk forge for my web application that allows my clients to save their model files and view them online. However, the problem I am facing is that the viewer is not unique for the clients as it runs on a client secret key. So, once I upload any model in the forge viewer, it appears to all the clients who are using it. So, how can I make sure that I only get the viewer that just opens the models that are present in the project of the client? Is there any way by which I won't have to use the access key so that the models do no get saved up alongside the viewer?
