DualSense Mute Button Light

Just curious, did a quick teardown just to see the innards. I put the controller back together and everything is good except for one thing, which isn’t a deal breaker just a little annoying, the light on the mute button. The actual mute button works, as I have it mapped for my toggle mute on discord, but for whatever reason the light won’t go on, any help on this? And if I need replacement parts can someone point me in the right direction? Thank you in advance!
