cancelAsMulti static method

Future<bool> cancelAsMulti({ required MultisigResponse multisigResponse, required Provider provider, required KeyPair signer, Duration storageKeyDelay = const Duration(seconds: 20), int tip = 0, int eraPeriod = 64, })

CancelAsMulti (Only the owner can cancel the multisig call.)

It cancels the multisig transaction.
