Background
Based on research from @dchen, it is common for Wikipedia editors to take discussions about an article to a third party destination and reference a conversation that originated on Talk pages. Presently, there is not an easy way to reference particular threads in a talk page from our app.

The Task
Build a "Share" button (in the toolbar or overflow menu, based on design) for a specific Talk conversation at the subject level.

i.e. After navigating to a Talk page discussion thread, show the three dots in the top right corner (LtR) of the screen, and once someone presses those dots, expose an option to "share" that discussion from the Talk screen mirroring the behavior of sharing a Wikipedia article.
