Now, all applications are stored on applications collection on Firestore
We will listen to the changes of the STATUS field on all applications' documents
To do this, we use Trigger feature of Firebase
Trigger flow
STATUS of an applications' document changes
Get clientId of the document
Get get client document from clientId
Get get phoneNumber of the client
Firebase Trigger listens -> start our code
With phoneNumber of the client, we send the SMS:
"Your loan application's status has changed from X to Y"
X: the previous status of the application
Y: the updated status of the application
