EntityAnalysis, Version 2 model in natural language API

[Ykost]

Hello,

could anyone share the python code on how to get natural language API to use version 2 for Entity  Sentiment Analysis?
The Demo can be run for that, but it seems like in the docs this part is missing:
https://cloud.google.com/natural-language/docs/reference/rest/v1/documents/analyzeEntitySentiment

However, for the classification, it is possible, as it is described here:

Thanks
