Sample Arduino Library with no Licence File

I purchased the SparkFun Ambient Light Sensor - VEML6030 (Qwiic) and it comes with Arduino sample code. This code compiles using the Arduino IDE but when I modify it for Particle Workbench or Web IDE, it tries to look for a non existing licence file and it does not go any further. Seems to be the case with the TinyGPSPlus library as well but strangely, this does appear in the Particle cloud Platform which i can use instead. How do i resolve for Particle Workbench? Is it a case of just copying any licence file from other shield libraries?

Also how do I delete my private library? I have some that I uploaded but it seems that once I upload the private library, it will then show a lock icon and cannot be deleted
