For multisig stream service, you can create instance in the following way.
const config = {
networkId,
nodeUrl,
streamContractId,
multiSigFactoryContractId,
},
const actions = {
multiSigActions: new MultiSigActions(),
storageSpecAction: new StorageSpecActions(),
streamActions: new StreamActions(),
};
const multisigService = new ZebecMultiSigService(
signerId,
multisigAccountId,
actions
);
