2020 4runner TRD pro touch up paint for black plastic on mirror arm

I haven't been able to find the color code to match the black plastic on the bottom of my mirror, it is the next piece below where the light insert would be on other models. I am assuming its on the assembly of the arm that sticks out. I'm not sure where I picked up the scratch from but its about 1 1/2 inches, tried buffing it out and it worked a little but I feel some paint would better cover it.

My trim code says LF22 and from my searches, I find black/graphite which doesn't tell me that much and Toyota has not gotten back to me on that either.
