[LWA] - (UI) Embedded UI on shared links

[qerdinger]

Describe the solution you'd like
Please create a banner which could be displayed when sending the shared link to the online collection.

Note : The access to the collection needs the user to be authentificated and authorised/allowed to access to the specified resources.

The header should only display public information if the user who previously exported the link decided to go that way.
