Help locating part for 2018 SR5, rear bumper cap with light or sensor?

Recently bought this used off a friend, definitely rough in some areas. The driver side rear bumper cap is basically being held in with tape (along with the tail light assembly), spent a while looking around at some sites but couldnt find the type of cap for the parking light or sensor this has. Also not sure if it will even hold if I try to install a new one with the rest of the bumper back that has been broken off. The light or sensor part on the left is still hanging on though Im not sure if its even functoning after the damage to that area. Trying to do it myself if possible, not a lot of money to put into it right now. Few pictures attatched of the passenger side thats still intact, and then the driver side with the cap on and off.

 

That is not a factory parking light sensor , somebody just screwed it on to the bumper , any compatible stock bumper end cover will work , can’t tell from the photos if other parts are needed for the install

 

okay thanks, that answers that question. The black plastic bit that the bumper cap actually fits into is missing on the driver side, but Im not sure if thats a single piece thats a part of the over all step up section, or if that can be replaced on its own

 

after looking at it for a bit and looking at some parts online I think its actually a part of the whole bumper so I dont think I can replace just the left hand side I might just need to get a new bumper entirely.
