TLJ shows us that Leia is force sensitive through the infamous “Superman Leia” scene, and at the end tells us she is going to help Rey with rebuilding the Skywalker lightsaber. then TROS opens on continuing where TLJ left off, by showing Rey train some basic moves under leia’s guidance. The movie then has a flashback later on explain that Leia started her training but stopped to save her son, which is why she only knows the more basic training circuits, yet she is still gifted in the force.
