Sharing of local pls files does not work

I can drag I drop local glb, and this generating sharing link works for me:
https://playcanvas.com/viewer?load=blob:https://playcanvas.com/2ac60cc2-53d4-4b0d-a51a-a87a9b7e598e

but when I do the same with ply file, this link:
https://playcanvas.com/viewer?load=blob:https://playcanvas.com/d9dd3618-aabe-438d-8ceb-b01c7b4d4e5a

gives me:

Actually, the first link only works as long as I have the viewer still opened in another tab.
The second link does not work in that case either.

We should hide sharing for local files, until this is supported.
