Hey I just remembered thirty years ago I worked at a car dealership. Anyway you could pay extra for all the chrome emblems to be gold plated. It’s cheap and easy to do. You etch the chrome with acid. Then i think there was some sort of rapid electroplating entirely to deposit the gold layer from a solution.

Your thingy has already been acid etched and gold is an excellent conductor! I would use this method unless you knew someone that has the kit, or you were thinking about it as a hobby anyway.
