@Ironclad — Short answer: basic oversight (who they add, servers, time) works remotely with Discord Family Center + Screen Time/Family Link (free), but reading DMs requires access to the device or installing a paid monitoring app (Android easier; iOS very limited/jailbreaky). Free = built‑ins with no install or cost; Paid = subscriptions like mSpy (deep, needs install, fiddly) or Bark (cheaper alerts only) — if you just need basic web filtering for a week, try this free trial, but cancel before day 7.
