Model the following process using Camunda:

• A customer contacted Bank of Beirut to ask for a house loan application form (We don't care how he contacted the bank. So it was a "message" of some sort.)
• The banks send the application form to the customer. If in a week, the bank doesn't hear from the customer they send him a reminder. We keep looping until the application form is received.
• Once an application is received, it is assessed. If it is viable the loan is approved. Otherwise, a rejection letter is sent to the customer.
