Back link to previous app from containing app progmatically in case of deeplinks

I created a keyboard extension with a scan button to open a barcode scanner in my containing app. When the scan is completed, it should navigate back to the initial app and the barcode data should be set as text to the textfield that initiated the keyboard and we clicked on scan button.


There is this app Scandit Wedge that does it the same way. But I couldn't find a way to achieve the same. Please refer GIF below.

Any help would be much appreciated.

Link is dead. did you managed to make it work?
