[Eikon Python API] How to specify the source in StreamingPrices?

I am looking for a solution to streaming data from a none default source. Notice there is a similar question raised last year:

https://community.developers.refinitiv.com/questions/41190/eikon-python-api-can-i-specify-the-source-from-whi.html

Where Alex mention streaming capability that will be able to retrieve market data from your TREP. And I am guessing it is StreamingPrices().

Say, in a spreadsheet I can use =RtGet(MY_SOURCE, MY_RIC, "Bid")

Is there any example I can follow to specify the source here?

I tried StreamingPrices(service = MY_SOURCE, instruments = MY_RIC, fields = ""Bid ). But it does not work.


Thanks in advance.
