I think I figured it out!
The BuddyPress Menu Type wasn’t visible in Appearances > Menu. To turn it on, I had to select Screen Options in the upper-right corner of the page and an entire set of checkboxes slide out. The BuddyPress checkbox must be selected and it will magically appear under Pages and along with the others (i.e. Posts, Custom Links, etc.). From there, you may gleefully add the BuddyPress links you want and voila!
This can be marked as resolved! lol
