This attraction is set shortly after the Battle of Crait from “Star Wars: The Last Jedi” in the official canon timeline.
This attraction will include a new character, Lieutenant Bek, a Mon Calamari communications officer for the Resistance who will guide recruits on their journey.
Guests can take home their own miniaturized version of the First Order Short-Range Evacuation Vehicle, another ride system featured on the attraction, thanks to a new playset that will be offered at First Order Cargo. The toy features details, lights, and sounds from the attraction, bringing it to life.
Actors from the sequel trilogy will reprise their roles in new scenes for the attraction, including Daisy Ridley (Rey), Adam Driver (Kylo Ren), John Boyega (Finn), Oscar Issac (Poe Dameron), and Domhnall Gleeson (General Hux).
Also that dialogue that I posted is at least from this description from Lt Bek.
