transferInterface with { owner } transfers tokens from an associated token account as an approved delegate. The delegate is the transaction authority. Only the delegate and fee payer sign; the owner’s signature is not required.
The recipient is a wallet address (associated token account derived and created internally)
The amount must be within the approved allowance
Each transfer reduces the remaining allowance

In the code examples, use createRpc() without arguments for localnet.
Get an API key from Helius and add to .env: API_KEY =< your-helius-api-key >
In the code examples, use createRpc(RPC_URL) with the devnet URL.
