overrideSystemFee?: string	This fee will override the system fee
invokeArgs?: InvokeArguments[]	Array of contract invoke inputs
broadcastOverride?: boolean	If this flag is set to True, the wallet provider will return the signed transaction rather than broadcasting to a node.
signers: Signers[]	Sender and the effective scope of signature
