how to get headers from xhr?

I'm trying to get the token from headers response, but I'm only getting "Content-Type", My JS code is very simple

get(url){
    const xhr = new XMLHttpRequest();
    xhr.open("GET", url)
    xhr.addEventListener("readystatechange", function () {
        if (this.readyState == this.HEADERS_RECEIVED)
            console.log(this.getAllResponseHeaders())
    });
    xhr.send(null)
}

the output is only "Content-Type: application/json"

if I to use the postman or browser I can see the "MyHeader", is important to emphasize that my request is a CORS request

You're going to need to set the appropriate CORS headers along with your response being sent from the url you are requesting. At the minimum, you'll need something like this:

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Methods: POST, GET");   
header('Access-Control-Expose-Headers: Custom-Header-Name');
