Welcome, I tried to Zap you some sats through this post but you don't have it set up.
Its really easy to set up just download Wallet of Satoshi from the app store
https://apps.apple.com/us/app/wallet-of-satoshi/id1438599608
https://play.google.com/store/apps/details?id=com.livingroomofsatoshi.wallet
Open the app click Receive
Then click the lightning address
It should now be copied. Go to your Nostr profile and paste it where it asks for a lightning address. Now people can send you some bitcoin ⚡️
