Noob Q: How do I export an zpub or xpub from a Core LN node wallet? I have elect-rs and RTL set up too if that makes anything easier. Just want to have a watch-only wallet available for the on-chain wallet.

Thanks, it outputs descriptors for wpkh, sh and tr. I want to import this to Sparrow but it requires to import a file (or scan qr) so I tried to just copy/paste the descriptors into a file and import that but then I get an error that it's not valid. Any ideas what I'm doing wrong here? What is the descriptors file supposed to look like?

Counterintuitively, in Sparrow you need to create a new wallet first, before you can import an xpub 😉. Just create a new wallet and then choose "xpub / watch only wallet"
