Since there is no public ICA auth module available at the moment, so set it nil as it is not enabled, See:
https://ibc.cosmos.network/main/apps/interchain-accounts/integration.html#disabling-controller-chain-functionality

The demo of the controller can be found the following repo, we should implement our own or waiting for the public one released.
