Your three department heads — Alex (Marketing), Elena (Finance), and Priya (Research) — each have a Telegram bot. Link once in Settings → Telegram (a short code), then delegate by DM exactly like the Console: same conversations, same sign-off rules, same grounding.
Documents arrive in-chat with inline Sign off / Send back buttons, so you can approve from anywhere. Everything you do on Telegram shows up in the web app too — it's one workplace with two doors.
