 - address: If nil, the address of the Safe account will be predicted based on the signer address.
 - paymaster: If specified, it will be used when preparing the user operation to sponsor gas fees.
 - safeConfig: If not provided, the default configuration will be used.
+- gasEstimator: By default will use an RPCGasEstimator.
