Does any one uses PCIex1 to dual NVME adapters?

Hello,

I have a h610m-hdv motherboard and i would like to add extra storage to it. After some search i found a PCIex1 to dual NVME adapter but i couldn't find anything about it online.

This is the product: https://www.aliexpress.com/item/1005005781156378.html

On the preview image a power connector is visible nobody mentions anything about it. Is it unused? What type is even that?

Do PCIex1 even supports bifurcation?
