Upload with URL

[R7JANV1]

Is your feature request related to a problem? Please describe.

Upload files with the app without logging in but with URL. Uploading large files via the browser does not work well.

Describe the solution you'd like

One could use the app to allow users to upload files via the app with a URL (which is authorized for uploading).

Describe alternatives you've considered

Instead, an account must be created each time to let users upload large data with the app.
