Add TInitial and TSuccess in MutationEventArgs

[codingki]

    I try to implement this, but I got this typescript error

const { sendTokensAsync, isLoading } = useSendTokens({
    onError: (err, args: SendTokensArgs) => {
      return toast({
        status: "error",
        title: "Send token fail",
        description: `Failed send token to ${args.recipientAddress}`,
      });
    },
  });

error
