NEM2 remove multisig account conversion fees

Technical Discussion
#1

Do I need fees to convert account to a multisig account?

I get Failure_Core_Insufficient_Balance, because the account which sign the aggregate account has not network currency.

What is the configuration I can made to remove it?

I have add UInt64.fromUint(0) to maxFee, but it still give same error:

    //MultisigAccountModificationTransaction
    const convertIntoMultisigTransaction = ModifyMultisigAccountTransaction.create(
      Deadline.create(),
      minApprovalDelta,
      minRemovaldDelta,
      multisigCosignatoryModification,
      NetworkType.MIJIN_TEST,
      UInt64.fromUint(0),
    );

    //AggregateBondedTransaction
    const aggregateTransaction = AggregateTransaction.createBonded(
      Deadline.create(),
      [convertIntoMultisigTransaction.toAggregate(multisigAccount.publicAccount)],
      NetworkType.MIJIN_TEST,
      [],
      UInt64.fromUint(0)
    );
