This code isn't working. I get owner.zap is not a function:

async function zap(npub) {
  console.log('npub:', npub);
  const signer = new NDKNip07Signer();
  const ndk = new NDK({
    explicitRelayUrls: ["wss://relay.follows.lol"],
    signer,
  });

  await ndk.connect();

  const owner = ndk.getUser({ npub });
  const invoice = await owner.zap(10);
}
