 **Note**: When a message is received/sent, due to signal sessions needing updating, the auth keys (`authState.keys`) will update. Whenever that happens, you must save the updated keys. Not doing so will prevent your messages from reaching the recipient & other unexpected consequences. The `useSingleFileAuthState` function automatically takes care of that, but for any other serious implementation -- you will need to be very careful with the key state management.
