Why can't ZIM SDK find offline messages in the room?

In the "room" scenario of ZIM SDK, offline message caching and retrieval are not supported by default.

If you need this, please contact ZEGOCLOUD Technical Support to enable the relevant permissions.

• After enabling this feature permission, in newly created rooms, users can call the queryHistoryMessage interface to query offline messages in that room.

• Rooms created before enabling this feature permission still cannot query offline messages.
