Shared Albums management

[tassoman]

Is your feature request related to a problem? Please describe.
Either in administrative panel or online documentation, I can't find the way to delete/expire/manage shared links.

Describe the solution you'd like
As user, I want to manage my shared album links, to make them expire or add/remove media items included.

Describe alternatives you've considered
If the feature already exists, I feel is not well documented, I can't find a way out to do that.

Additional context
Sidebar is missing a "shared links" menu option
