You can go through the same steps you followed to sync your ZERO:
- In the Rabby browser extension, click on the "Add an address" icon in the top right and then "Connect Hardware Wallets" → "NGRAVE ZERO".
If prompted, allow Rabby access to your webcam. - Because you already have a hardware wallet synced, you will get a list of your ETH accounts instead of the camera.
- To disconnect your ZERO from Rabby, deselect all the accounts that are currently linked to Rabby Wallet.
