French audio in manual stream selection from InputStrem Adaptative

Dear all,

*I'm submitting a feature request and support request

## General information

LibreElec 9.1.501 / Kodi 18 on my Pi 4 (4gb) /
CastagnaIT 1.0.0 with NetFlix 0.15.3 from repository

### Description
**What works...**maybe interesting for other French people...
In "Auto" as my player settings are audio French and subtitle French, I get always the French video/audio stream in NetFlix addon but I cannot select the bps quality and when it is more than 2'500000 bps, the Pi4 is not powerfull enough ! My workaround so far is to use Inputstream adaptive with a Max. Bandwidth set to 2'800 000 !
**My issue...**
So I would like to use Inputstream adaptive in "manual" stream mode but never find French Audio Stream upt o now (only German/Spanish/English)

**Is it possible to get an NetFlix 0.15.3 zip with FRENCH-ENGLISH-GERMAN ?
Even better, why not adding/opening automatically a dialog box when selecting "manual" mode stream in Inputstream adaptive to be able to select the languages of interest ?**

Or can someone explain me which file I should edit to force searching for French audio stream in manual stream mode ?
Has it someone to do with the file MSLv2.py ?
In this case where can I find it ?
Can we modify it with Putty in SSH using nano editor command ?

All help is welcome... I saw only one request for French audio so far and nobody answered !

Thank you in advance

Start by locating the mentioned MSLv2.py file and reviewing how manual stream selection handles audio languages in the Netflix 0.15.3 addon. Check the InputStream Adaptive manual-selection flow and its language handling. Done means French audio is available in manual mode, or a language-selection dialog is defined and works as requested.
