"Usage"

### Feature:
use case to only get the iFrame Link of an object for external use.

We integrated it to the upload form first, but decided it makes more sense to integrate this function to the standalone viewer.

No source files or tests are named. Start with the linked issue and designs, then locate the standalone viewer's public embedding entry point; done means the viewer can provide only an object's iFrame link for external use.
