Parts request + questions :)

[Orion Pobursky]

- Who is doing the match in Stud.io to match to the LDraw ref/to the right part?

Presumably the Stud.io team. While we have tried to reach out, we have no official (or unofficial) involvement with them.

- Are you talking about this app for BIA : https://apps.microsoft.com/detail/9nblgg...r-FR&gl=PG ?

No the LEGO Builder app for Andriod and iOS:
