Uh, that’s not good.
Here are some other repositories hosting cordova-webintent that may or may not be the same:
- https://github.com/pscholl/cordova-webintent
- https://github.com/marcelchastain/cordova-webintent
- https://github.com/chrisekelley/cordova-webintent
- https://github.com/GroupAhead/cordova-plugin-webintent
The last one acknowledges the disappearance of Initsogar and wants to be a substitute, so I assume it should be a good replacement for your usage.
