from @art-lowel: Observable for currentOptionId

Browse Source 
Next in order to know what page we're on, I use the route.url observable angular provides us that contains the current url, pipe that through a filter to ensure it has a value for the map below, which will just get the last part of the current url, so the community or collection id, or the type of the browse page.
