Performing ntlm authentication in jquery ajax GET call

Question

I couldn't find anything on SO that matches my requirement - only one or two questions that had some similarities but nothing close to mine. There is this that is a mish mash of different possible 'solutions' that doesn't address my req: Javascript/Ajax NTLM Authentication. Plus - it's 5 years old and seems to be more of .net code.

My requirement: I'm trying to access a csv file on a remote server, by doing it in a jquery ajax call. The remote server is a sharepoint server that hosts the csv file. The remote server is setup with ntlm authentication.

What I've done so far: I'm able to successfully access the said file from Postman by doing a GET call, and passing in the username and password in the 'Authentication' tab (of Postman) and setting the 'Headers' values as 'Authorization = true' and 'Accept = application/json' values (in Postman). I'm able to retrieve all the rows of the csv file including the header row.

I need to REPLICATE what I'm able to successfully do via Postman (posted above) in a jquery ajax call (ie: pass in the relevant ntlm authentication info), and retrieve the rows from the csv file.

I currently have the following code but have no idea of how to perform the ntlm authentication in jquery:

 $.ajax({
                url: "https://xxxxx.yyyyyy.com/abc/def-efg/hijk/MyFile.csv",
                type: "GET",
                headers: {
                "ACCEPT": "application/json;odata=verbose"
                },
                success: function(data){
                var results = data.d.results;
                for(i=0; i < data.d.results.length; i++){
                    console.log(i + data.d.results[i].Title);
                }
                }
            });

I have the necessary 'domain', 'username' & 'password' info, but need some guidance on how to go about incorporating that info into the code above. P.S. I tried the ntlm plugin that someone posted on the 5 year old question thread on SO (which I posted above), but it didn't work for me (I didn't see any output or errors in the chrome console). That code is as follows:

Ntlm.setCredentials('MyDomain', 'username', 'password');
var url = 'https://abc.def.com/sites/xyz- 
Home/myfiles/MyFile.csv';

            if (Ntlm.authenticate(url)) {
                var request = new XMLHttpRequest();
                request.open('GET', url, false);
                request.send(null);
                console.log(request.responseText);
                // => My super secret message stored on server.
            }
