Just wanted to add a little context from our chat last week about what will be required on the SDK/binding side.

• LIBXMTP Bindings
  • A function to initiate a request to upload messages
    • This uses a new topic to send a message with a pin for user validation
  • A function to trigger a upload of messages
• SDK
  • A new topic for message history (only for handling in push notification)
  • Subscribe functionality for these new topics (subscribeToBackupRequest)
    • This listens for the new topic messages and if validated triggers an upload of messages
  • Send new topic for this event (sendBackupRequest)
    • Triggered on new installation logins

For anyone finding this tracking ticket: there is also this companion repo to handle the temporary storage and relaying of the message bundles.
