If a current Baaz user receives an invitation, they must click on the link that will transfer them to the application and a pop-up screen will appear requesting to accept/reject the authentication request.
For new users, they will be transferred to the Applications store (Google Play, Apple Store) to download the application. They must then proceed to complete the steps of registration and documentation of their accounts. After this step, they will be shown the pop-up screen for authentication.
If the connection or operation is interrupted for any reason the user can return to the link in the message and press it again to complete the process.
