help me with a javascript npm library

Hi, I understand you want to work on the existing Power BI library code to add an extra URL parameter. I can do this for you, all you need to do is specify the type of parameter you want to add and answer a few questions. I'm a Javascript developer with years of experience and I've worked on libraries in the past, I have also worked with Power BI. Feel free to contact me about the details of the project or ask any questions.
