Yes, it's the nostrconnect:// uri
You can also send the uri directly if you don't want to show a qrcode
This looks awesome but what dose the QR code scanner do? Is it finally the part of NIP-46 that supports connections created by the client? https://github.com/nostr-protocol/nips/blob/master/46.md#direct-connection-initiated-by-the-client

awesome, I'll look into adding support for that in noStrudel. it would be cool to have the app show a qr code and then scan it with my phone to login
