Wired Doorbell 2k - is it saving recordings on HB3?

I installed my new Doorbell (dual camera) - appeared to install with my Homebase 3. I also understood that a HomeBase was required. All went well, and completed successfully.

However when I go into settings it appears the recordings are being saved locally? Saying total 6.6

gig. My HomeBase3 has 1tb free.

I can’t find a place to select the HB3 as a storage destination…

Any one help answer my question?
