GM_xmlhttpRequest POST request not working cross-domain

I'm running a script in Tampermonkey, and I'm trying to use the GM_xmlhttpRequest method to send a POST request cross-domain. However It's not working for me. In the console I just get normal cross-origin the error:

XMLHttpRequest cannot load [domain1]. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin [domain2] is therefore not allowed access.

It's my understanding that the whole point of the GM request method is that it supports cross-domain unlike XMLHttpRequest(). So I'm not seeing why this will not work as it should. Here is the gist of what I'm doing:

// @match      https://[domain2]
// @grant      GM_xmlhttpRequest

GM_xmlhttpRequest({
    method: "POST",
    url: "https://[domain1]/exmaple.php",
    data: formData,            
    onload: function(response) {}        
        console.log(response.responseText);
    }
})

Maybe I'm missing something simple or I have the wrong idea

edit: I suppose I should note that the above code is nested inside a different normal XMLHttpRequest in case that would affect it.

Turns out that the "Unsafe window retrieval" setting in Tampermonkey just needed to be set to Native. Seems to be working now
