    function fund() public payable {
        require(msg.value.getConversionRate() >= MINIMUM_USD, "You need to spend more ETH!");
        // require(PriceConverter.getConversionRate(msg.value) >= MINIMUM_USD, "You need to spend more ETH!");
        addressToAmountFunded[msg.sender] += msg.value;
        funders.push(msg.sender);
    }

TypeError:

You are calling the function getConversionRate() without giving it an argument for the priceFeed in your require statement. Your fund function's require statement should look something like:

require(msg.value.getConversionRate(s_priceFeed) >= MINIMUM_USD, "You need to spend more ETH!");

where s_priceFeed represents the AggregatorV3Interface object that you should have initialized through your constructor. Something like this:

constructor(address priceFeed) {
        s_priceFeed = AggregatorV3Interface(priceFeed);
        i_owner = msg.sender;
    }
