Hello #nostr family

I need info

I just download amethyst and they ask me to chose a relay for direct message. All the relay propositions are not free. Someone know one or 2 free relay for direct message. And why it's needed on amethyst and not others ?

nostr:npub1wfpr8aulg4q63zjyte5ufljrq9j8vr4gptpkqx58falr732ep85stwh463 do you have info ?
