Neo Trinkey capacitive touch: is there a compatible / form factor for breakout adapter?

hello,

I have an Adafruit Neo Trinkey (SAMD21 USB Key)

I am using the capacitive touch part of it to attach with crocodile clips and cable to use it as a mini theremin.

I was wondering if the end of this key is based on some sort of standard/form factor which would allow me to slot a breakout connector thingy to it, rather than soldering directly to the key.

Doesn’t look like any kind of connector I’ve seen before, don’t think it adheres to any standard.
