Replicating Excel Add-ins function to Python

Hi,

I am looking for data for closing auction, intraday auction and opening auction for stocks and ETF

I am looking to replicate the below excel function into python:

1. =RHistory("BMWG.DE";"NDA_RAW.Nda_closing_auction_volume;NDA_RAW.Nda_close_auction_price;NDA_RAW.Nda_date";"INTERVAL:1D";;"CH:Fd";B2)

I tried to replicate this in python using command:

```

import eikon as ek

ek.get_data(['BMWG.DE'],["TR.CLOSINGAUCTIONVOLUME","AUCTN_DATE"],{'SDate': '2020-02-01','EDate': '2020-02-21','Frq': 'D' })

```

Although it gives me the closing auction data as below, but it fails to show to auction date. Is there any possibility to replicate the above excel add-in command into python? Thanks.
