Herelink disassemble

My Herelink’s left stick got a little bit weird.
It feels like some wire interfere the spring of the left stick.
The yaw control can’t get back to the midpoint normally.
And it’s annoying when I takeoff a drone and spin around with the yaw axis.
I try to disassemble the Herelink but can’t see how to do it.

Please contact your reseller, we will not RMA it if you disassemble it.

If disassembly isn’t planned for then how is one supposed to remove the spring on the left stick for throttle control?
