How to upload a large size file(more than 250MB) on sharepoint via rest API callout in JavaScript?

I am trying to upload a large file on sharepoint via rest api callout using JavaScript but not able to upload files having size more then 250MB.

Below mentioned is the logic that I have implemented -

<html>
  <head>
    <title>File Upload with Fetch API</title>
  </head>
  <body>
    <form>
      <input type="file" id="fileInput" name="fileInput">
      <button type="button" id="uploadButton">Upload</button>
    </form>

    <script>
      const uploadButton = document.getElementById('uploadButton');
      const fileInput = document.getElementById('fileInput');
	  accesstoken='{ACCESS_TOKEN}';
      filename ='Test1.pdf';
      const endpoint = 'https://<Tenant Name>.sharepoint.com/sites/<SiteName>/_api/web/GetFolderByServerRelativeUrl(\'' + '/sites/<SiteName>/Shared%20Documents/<FolderName>' + '\')/Files/add(url=\'' + filename + '\',overwrite=true)';

        uploadButton.addEventListener('click', () => {

        const file = fileInput.files[0];

        const formData = new FormData();

        formData.append('file', file);

        fetch(endpoint, {

          method: 'POST',

          headers: {
            'Authorization': 'Bearer '+accesstoken,
            'Content-Type': 'multipart/form-data',
            'Accept': 'application/json; odata=nometadata',
            'X-RequestDigest':'<FORM_Digest>'
          },

          body: formData

        })

        .then(response => response.json())

        .then(data => {

          alert('File uploaded successfully!');

        })

        .catch(error => {

          alert('Error uploading file');

        });

      });

    </script>

  </body>

</html>

By this logic I am able to upload files on SharePoint but of size less than 250MB.

If I try to upload file greater than 250MB it throws error in response, which is below mentioned -
