Certain channels, especially E-wallet support Tap & Pay functionality, enabling seamless transactions with just a tap, primarily in a mobile device flow. To ensure proper handling of transaction notifications, it is required to add an event listener that manages the app URL or Universal Link, facilitating a smooth user experience and ensuring the app responds appropriately to the incoming data.

Implementation:

Adds an event listener to detect when the system is redirected to a specific page (triggered URL).
When an app URL or universal URL is triggered after the webview reaches a specific page, the opened URL will be opened with new intent.
When a channel mobile app is opened to proceed payment, it is optional to update the specific page and redirect it to a self setup loading page, which will have continuous checking transaction status in a certain timeframe. (E.g., 5 minutes waiting time with 10 seconds interval time)
