That is a specific feature about paper wallets. The only thing it will do is create an on-chain tx to send the sats from the paper wallet to your Relai wallet. The wording is a bit misleading indeed

Then I don't know how to use it.
What I'd like:
1) Enter my xpub
2) buy with relai
3) receive funds on my first address of the xpub which didn't have any transactions...
Preferably an easy connection between Ledger/BitBox and Relai..
