How to reference a contract’s library function in hardhat testing

I have a contract that uses an eth/usd price feed library to convert a uint value into its USD equivalent. pragma solidity 0.8.0; import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol"; library PriceConverter { // No state variables inside of libraries // All functions must be internal function getPrice(AggregatorV3Interface priceFeed) internal view returns (uint256 _price) { (, int256 price, , ,::Listen

I have a contract that uses an eth/usd price feed library to convert a uint value into its USD equivalent.

pragma solidity 0.8.0;  import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";  library PriceConverter {   // No state variables inside of libraries   // All functions must be internal    function getPrice(AggregatorV3Interface priceFeed)     internal     view     returns (uint256 _price)   {     (, int256 price, , , ) = priceFeed.latestRoundData();     return uint256(price * 1e10);   }    function getConversionRate(uint256 ethAmount, AggregatorV3Interface priceFeed)     internal     view     returns (uint256)   {     uint256 price = getPrice(priceFeed);     uint256 ethAmountInUsd = (price * ethAmount) / 1e18;     return (ethAmountInUsd);   } }  pragma solidity 0.8.0;  import "./PriceConverter.sol";  contract Foo {   using priceConverter for uint256;   MINIMUM_USD = 7000000000000      function bar() public payable {      require(msg.value.getConversionRate() > MINIMUM_USD)   } }  

In my hardhat test I am trying to call the getConversionRate() uint256 function in my contract to test some values, but I am unsure how to access it.
