Need help finding the threaded nut/end cap for Canyon Neuron AL 2017 rear suspension pivot axle

Hi everyone,
I’m trying to find a replacement part for my Canyon Neuron AL 2017 rear suspension linkage.
I still have the axle/bolt shown in the photo, but I’m missing the threaded end piece / nut / female side that screws onto it.
If that small threaded part cannot be bought separately, then I’m looking for the complete axle assembly (both pieces together).
I believe this may be part of the main pivot hardware, but I’m not completely sure.
Does anyone know:
the exact name of this hardware?
the Canyon part number?
where I could buy it?
or if another Canyon model uses the same pivot assembly?
Photo attached.
Any help would be greatly appreciated. Thanks!
