Returns when the authenticated caller last gave peer recognition to each of the
specified users. Pass up to 20 user IDs; the response includes one
entry per requested user with a last_recognized_at timestamp (null when the
caller has never recognized that user).

Use for "Have I recognized these people recently?", "When did I last give
recognition to each of my teammates?", or "Which of these users have I never
recognized?".

All user IDs must belong to the caller's company. The caller's own ID is
accepted but last_recognized_at will always be null (you cannot recognize
yourself). Duplicate IDs are deduplicated before querying.

Required OAuth scope: recognition:read or recognition:administer
