const vault = await Vault.load(LOCAL_ENV, connection, vaultAddress);

// Collect all available interest
const ix = vault.ixCollectInterest({
  owner: wallet.publicKey,
  amount: amount("All"),
});

const tx = new Transaction().add(ix);
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);
