Execute arguments

useApproveAllowance supports two shapes of arguments:

type AllowanceArgs = {
  owner: string | AccountId;
  spender: string | AccountId;
  amount: number | Hbar;
};

type TokenAllowanceArgs = {
  tokenId: string | TokenId;
  owner: string | AccountId;
  spender: string | AccountId;
  amount: number;
};

If tokenId is present, a token allowance is approved; otherwise an HBAR allowance is approved.

  flow: FlowHandle<TransactionReceipt>;
  execute: (args: AllowanceArgs | TokenAllowanceArgs) => Promise<void>;
}
