Do I need to grease or replace the latch (the latch behind the backseat that connects to the trunk)?

Car: 2019 Genesis G70 2.0 AWD - 68k miles

I had a hard time pin pointing the issue but I tested driving with the backseat down and with the backseat in standard position. It creeks when it’s up and doesn’t creek when it’s down. Only tried it twice so i’ll continue to drive with the backseat down this week to confirm the theory.

Any idea what causes this? Is it because some part of the latch system is loose or doesn’t have grease?
