Permissions for Controller.genericCall

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?
