Brave talk UI default language

Every time I start Brave Talk it is in english, in spite of the UI language of the Brave (its set to polish). I’m setting Brave Talk UI into polish but when I close it and come back to this feature, it’s in english again.
So, for me., it should use language preferences from browser’s settings.
It would be an interesting add-on, an option to set UI language for sharing link generated within app, so I could generate different sharing links for different users to the same meeting (it’s is common I have a meeting with french, polish and english speaking people).
