Upload guest links should have a cleaner interface

Actually the interface is not bad, but it should not have the login button since it is supposed to be a dedicated link for the user to send you something.

For example NextCloud presents such links in this way:

It would be very interesting if the upload interface was similar and did not show the login icon (or at least have an option not to do so).

Thanks for the suggestion! It might be possible to adjust the template so that the guest upload page has fewer extraneous elements.
