How to make a complete backup/restore of FIDO2 credentials?

[Darkeudo]

Hello,
I'm using PicoForge with pico-fido and I need to make a complete backup copy of my security key, including all registered FIDO2 credentials.
I tried using picotool to make a complete flash dump, The new key will no longer accept the PIN when the PIN is entered.

How to access the backup functionality with 24 words in PicoForge?
How to use the Rescue interface to clone a complete FIDO security key?
Is it possible to do a backup/restore that includes ALL existing FIDO2 credentials, not just regenerate them from the seed?

Could you guide me on how to make a functional backup copy of my primary key to use as a backup in case of loss?
Thank you.
