If you need a NIP5 and you use Lightning Tip Bot ( LN.tips ) you can add your npub in your wallet and then use your [email protected] as both your zap ⚡️ wallet and your NIP5 identifier.
To add your npub, reply to the bot in telegram with the following (screenshot below for reference):
/nostr add <your npub>
You’ll get a confirmation message with a ✅. Then just set it as your NIP5 in your Nostr profile.
