Please follow the instructions provided by Outsystems team. The instructions are available here: https://youtu.be/Idugwok3aPg?t=562
Use our official BlinkID - phonegap plugin located here: https://github.com/BlinkID/blinkid-phonegap
The plugin is located in the BlinkID folder in that repository (it's not in the root!).
If this still doesn't work, please let me know the exact steps which you used to integrate the plugin into the Outsystems app.
