How to thread leg-lifter strap on Tempest 165

Help! I removed the seat from my friend’s Wilderness Systems Tempest 165 kayak I was paddling and now I can’t figure out how to thread the strap for the leg-lifter.

She’s taking the kayak on a great lakes shoreline trip this weekend, so I have to get it together (ideally today because I was heading home today).

I’ve submitted a support request but hoping I might get a faster response here.

This might help
