TJR - Higher 2.0 vocal glitch... thing

First of all, the track:

Starts with the chorus at 1:30

Ok, so it’s the vocal stab that turns into some kind of pitch-down thing. I honestly can’t figure out how it’s done other than taking a vocal sample, throwing it into something like Simpler, shortening the sample length by a significant amount, and maybe transposing it down a lot to get that clicky quality.

Any help would be awesome!
