Can I submit a new expense for a team member through the AI?

Yes! Use the `create_expense` tool. You will need to provide the engagement ID, expense details (name, description, category, date), and the receipt information including the amount and currency.

How do I check which countries Oyster supports for hiring?

Simply ask the agent to run the `list_hiring_countries` tool. It will return a list of all countries where Oyster currently facilitates global employment.

Is it possible to track the status of a request I just created?

Yes. For asynchronous operations like creating expenses, you can use the `get_operation_status` tool with the operation key provided during creation to check its progress.
