thanks for taking the time to contribute that integration!
Before we can get started with the actual review process there is one thing to sort out: We require our 3rd party libraries to be hosted in public repositories, with an OSI approved license and tagged releases, which get deployed to PyPi through CICD. I wasn't able to find the source code of the library (as in the actual repo, not pypi), can you point me to it?
