Multi-turn tool-use scenario.
Tools involved: MessageAPI
TradingBot

User requests (one per turn):
user: It would mean a lot if you could include Quasar Ltd.'s stock in my watchlist. After that's completed, please let me know what's on the list so I can have a look.
user: I need to see the details of each stock in my watchlist to feel reassured. Once I have that information, I am good to go.
