Call Python SSE function in qlik extension Java script

[#1]

Dear all,

I am trying to use Qliksense Server Side Extension for Python

server-side-extension/examples/python at master · qlik-oss/server-side-extension · GitHub

I am able to make Python Server run and from Qliksense, call the functions in chart expressions to Python Server (e.g., Column.SumOfRows(A,B))

https://github.com/qlik-oss/server-side-extension/blob/master/examples/python/ColumnOperations/READM...

Now, I want to build one visualization extension to visualize the result returned from Python Server. However, I get stuck as I dont know how to call the function in Javascript (Column.SumOfRows(A,B)). Do you know how to handle this? Thank you very much.

Best regards,
