In Solo, what is the name of the “droid rights” activist droid?

The story behind the answer

Lando Calrissian’s outspoken co-pilot in Solo campaigns for droid emancipation and sparks the Kessel droid uprising—hence the “droid rights” label. By contrast, K-2SO is the reprogrammed Imperial security droid from Rogue One; C-3PO is a protocol droid preoccupied with etiquette and translation; and R2-D2 is a heroic astromech, not an activist.

Built from mismatched parts and voiced by Phoebe Waller-Bridge, this droid’s independent streak is central to the film’s themes of autonomy and freedom. After being critically damaged, her navigational matrix is integrated into the Millennium Falcon, offering a lore nod to the original trilogy’s line about the Falcon’s “peculiar dialect” and helping explain the ship’s uncanny navigation abilities.
