Let's create/onboard a new buyer. For this you'll need 2 things:
- Create a new ID for this buyer (should map to your internal identifier)
- The buyer's legal information. ⚠️ Note that one of either business_registration_number or tax_number must be provided on creation.
You should create a buyer entity for every buyer on your platform that can be part of a lending transaction.
