npm-license-crawler cannot determine license

[mppperez]

Trying to generate license.js file with npm-license-crawler leads to "UNKNOWN" license entry for this library:

...
    "react-native-elapsed-time@0.2.0": {
        "licenses": "UNKNOWN",
        "repository": "https://github.com/pankajkgarg/react-native-elapsed-time",
        "licenseUrl": "https://github.com/pankajkgarg/react-native-elapsed-time",
        "parents": "xxx"
    },
...

Would it be possible to fix that at npmjs: https://www.npmjs.com/package/react-native-elapsed-time ? By setting the license there it should be possibly to automatically fetch that information and with that automate the process to list used libraries + their licenses in apps.
