POST Request is working on Postman but getting 403 in JS

I have tested an API https://connect.us-east-1.amazonaws.com/contact/suspend-recording with POST request in postman successfully and getting the 200 statuscode and it is working absolutely fine and suspend/pause the call recording according to the desired goals.
I generate the code by using POSTMAN Code Snippet and used it in my project/code and than when i test it, it throw 403 forbidden error.

function pauseRecording(){
//let contactId = contactId; //document.getElementById("contactId").value;

alert("ContactId Alert:" + contactId)
var settings = {
    "crossDomain": true,
    "url": "https://connect.us-east-1.amazonaws.com/contact/suspend-recording",
    "method": "POST",
    "timeout": 0,
    "headers": {
      "X-Amz-Content-Sha256": "beaead3198f7da1e70d03ab969765e0821b24fc913697e929e726aeaebXXXXXX",
      "X-Amz-Date": "20220324T135827Z",
      "Authorization": "XXXX-XXXX-SHA256 Credential=XXXXXXI7HVAVPV5LNWQN/20220324/us-east-1/connect/aws4_request, SignedHeaders=host;x-amz-content-sha256;x-amz-date, Signature=XXXXXXde1fc213ebf2191ebc518e01858fb6cc024773db9133deb7fbebc59XXX",
      "Content-Type": "application/json"
    },
    "data": JSON.stringify({
      "ContactId": contactId,
      "InitialContactId": contactId,
      "InstanceId": "XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
    }),
  };
  
  $.ajax(settings).done(function (response) {
    console.log(response);
  });
}

HTML Button: <button onclick="pauseRecording()">Pause Recording</button>
Any Solution Please?
