Permissions for Controller.genericCall

[LeibnizCapital]

The peepeth scheme does this:

        Controller controller = Controller(_avatar.owner());
        // Sends a call to the Peepeth contract to create an account.
        // The call will be made from the avatar address such that when received by the Peepeth contract, the msg.sender value will be the avatar's address
        controller.genericCall(
            peepethContract, 
            abi.encodeWithSelector(PeepethInterface(peepethContract).createAccount.selector, _name, _ipfsHash),
            _avatar,
            0
        );

I tried the same in my own dao but it reverts. I can do a normal myContract.call with the same encoding. What part of the implementation gives it the permissions to call. Is it inheriting UniversalScheme?
