Been using as PWA for many months. Where do I place the NWC credentials in amethyst ?
"Can't" scan QR since on same device
Use Mutiny & Alby with NWC as well before, so not new to NWC

You need to split your nwc credential string, it has such format:
nostr+walletconnect://PUBKEY?relay=RELAY&secret=SECRET
You can generate them at https://nwc.getalby.com for Alby Accounts
Great thank you
