Hello team, could you please help us get the Order Book with Eikon API - preferred in Python or R

We have an important demo for a significant client and we wish to advance with this request.

This is what I got so far

import refinitiv.dataplatform as rdp
import eikon as ek
import pandas as pd
import plotly.express as px
import time

rdp.open_desktop_session('DEFAULT_CODE_BOOK_APP_KEY')
ek.set_app_key('DEFAULT_CODE_BOOK_APP_KEY')

fields = []
for i in range(1, 10):
    fields.append('BEST_BID' + str(i))
    fields.append('BEST_ASK' + str(i))
fields = fields + ['BEST_BSZ10', 'BEST_BID10', 'BEST_ASK10', 'BEST_ASZ10']
ek.get_data('BBDC4.SA',fields)

But those fields are not found for RIC < BBDC4.SA >.

Another question is if client could get streaming book in R with Eikon API?

Thanks
