Issues with my backlight after minor water spill

I spilled a bit of water on my MacBook Pro 2019 13" and I'm having some problems with the backlight. The device is still fully functional but I'm worried down the line it will stop working. Currently however, backlight flickers often and has really uneven lighting. From what I can see there is 7 spotlight like light sources at the bottom of my screen evenly placed with dark spots in between. how ever these don't effect the rest of the screen. I'm just wondering what I need to do to fix this.
