How to make a glitch effect like the one in this video

Hello, a while back I found some online outro maker and used it to make the outro in this video https://www.youtube.com/watch?v=NrB7VqVcAio&t=932s However, now I would like to make that again in premiere. I can do the RGB shift thing but not the lines flicker. Could someone point me towards somewhere/somebody who knows how to do this.

Note: I can also use After Effects as well if needed.
