Penta sata hat pcie fpc where to get?

Hi,

i bought a RockPi4 togehter with a penta sata hat. As i didn’t had any use for the penta sata hat before, i used the RockPi4 for home automation purposes. Now i read, that the penta sata hat can be used with a raspberry pi 5, too. Unfortunately i need a pcie fpc cable for that. Where can i find one? Is it available by radxa?

Kind regards

You can find them on arace or maybe on allnet.china (they unpublish unavailable items, so it may come up).
