Water damage, need component of schemat

Hi, after water damage, the Touch Bar does not power on. I purchased a new bar, but found different damage and need to know the type and the value to potentially replace it. Not sure if that is a bar bar-related thought.

Looks like a resistor to me, but need to find a value and the size. Not sure how to describe a connector where the component is places, so hopefully somebody will recognize it.

Have a look at the images. It is a MacBook Pro 15-inch 2018.

@michalaugu27500 that is an inductor (Ferrite bead chip). Reference designator for that is L8504 and it is a FERR-120-OHM-1.5A in a 0402 package. Something like this will work. Mouser is heavy on shipping costs so make sure you make ordering it worth the cost of shipping. Of course, you can purchase wherever you like. The link is just an example since I purchase my components either from Mouser or Digikey, but it is not an endorsement. No, I don't receive kickbacks :-))

The trace is gone, and I think the left side burned was a vias, and it's gone as well. You don't have a schematic, do you? I wonder if I can route it somewhere else.
