Major cue differences for this lift vs deadlift and RDL are a) push the hips up, not back, and b) push the knees back to maintain their namesake “stiffness” throughout.

Also keep in mind, that, although you do touch the floor at the bottom of the eccentric, do not release your breath or muscular contraction with that touch. Unlike a conventional deadlift, keep full muscle tension through that touch and until the top of the concentric portion where you “lock out” and reset for another rep.
