Scheduled reminders and delayed send for DSH: /later delivers what you type as yourself at the time you pick, while the timer panel (or /schedule) posts a reminder row — even with the page closed. (scheduled send / reminders / delayed send)

Scheduled send: fire a drafted message into the bound conversation as a normal user bubble at a set time. Runs host-side, so the browser can stay closed; per-session isolation and restart-safe redelivery.

Timed send for the chat composer: pick a moment and the host delivers the message then. Inside an existing conversation tasks join that conversation; from the new-session screen each task gets its own pre-created session.
