How can I use the "Functional Testing Library"?

On the Examples pages is mentioned this library:

Functional Testing Library – A Java library for functional testing of Daml applications.

but no link is provided. How can I use this library?

It refers to this library GitHub - digital-asset/lib-daml-jvm-test: A library providing functions for testing DAML applications on JVM.. The readme has relatively detailed instructions on how to use it.

Thank you!
