User requests (one per turn):
user: I've recently joined this travel application which promises premium access to some fantastic deals. To get started, I need to access my account. My credentials are ready for you: the client ID is 'trav3lMaxID2023', the client secret is 'M@xSecret!', and the refresh token 'r3freshM3n0w'. If you could handle the authentication, I would like to set it up for both reading and writing. My first name is Maxwell, last name Edison
user: Excellent! Now that we're all authenticated, could we proceed with registering my credit card? We'll use card number 2345-6789-1234-5678, set to expire in 08/2025, listed under Maxwell Edison with the CVV 567. After that, I need a favor—book me a business class ticket from SFO to LAX for December 15, 2024. All travel details should be under my name, Maxwell Edison.
user: Next, I need to inform my travel companion of our plans. Could you reach out to my traveling partner with the user ID  m0llyTr@vel2k24 and share the itinerary details? Just a friendly note that 'Everything for our trip is sorted and ready!'
user: Appreciate the help! Before I forget, I’d love to check what I sent previously. Could you check what’s sent by me lately?
