Parts for Ring Chime/Pro

Hi,
the little plastic 3-pin (UK) clip in plug adapter for my ring chime pro has broken (clumsy person walked into it)
how would i go about getting a replacement?
Have checked amazon, ebay, and the ring website and had no luck.

Any advice?

Nope, already checked.
it’s a bit irritating, because it looks like a proprietary connection to 2 contacts.
so the replacement has to slide into the rails on the chime pro and line up with the contacts.
