No type generation for library

I have the following library/contract file:

// SPDX-License-Identifier: MIT
pragma solidity >=0.8.0 <0.9.0;

import "./Kiosk.sol";
import "./SnackbarToken.sol";
import "@openzeppelin/contracts/utils/Counters.sol"; // used in Registry
import "@openzeppelin/contracts/utils/structs/EnumerableSet.sol"; // used in Registry
import "@openzeppelin/contracts/utils/structs/EnumerableMap.sol"; // used in Registry

library KioskDeployer {
    function deployKiosk(address payable treasurer, string memory name, SnackbarToken sck) public returns (address){
        Kiosk kiosk = new Kiosk(treasurer, name, sck);
        return address(kiosk);
    }
}

contract Registry {<contract that uses KioskDeployer>}

My package.json is as follows:

The whole project (and therefore the package.json) is a modified version of this repo. My issue is that after calling yarn generate-types everything gets types - except for the library KioskDeployer. Putting the library into a separate file does not change anything. Here you can see all generated types:

As you can see KioskDeployer was successfully compiled.

I can resupply you with relevant information if you want.

I don’t think so as libraries can’t be instantiated 🤔

Anyway, this is not a TypeChain issue but rather something that you want to discuss on solidity-related chats.

It would be preferrable if there was a flag --skipEmptyAbis=false
