[Suggestion] - Allow logging in directly from a document

Hello,

I landed earlier on a document, using a guest account. Since I'm not a regular user of CodiMD, it took me "a little bit too much" time (to my taste :) ) to find how to log in. That is, going back to the home page, then finding the document again. This is a bit annoying as a end user.

Suggestion : add the possibility to log in directly from the document, then automatically redirect the user to this document (that is... if a page change is needed to log in) after connection.
This would be a good feature, I think.

Start by tracing how a guest reaches a document and how the existing login flow is entered. The feature is done when a guest can log in directly from the document and is automatically returned to that document after authentication.
