Why Annotation tools not appearing on my PDF?

Hi,

I am using an iframe to render PDF in div tag as per the documentation. I have included my registered client id for my pdf embed api. I have also included embed mode as Inline and showAnnotationTools: true. Still I do not see Annotation tools appearing on PDF viewer. Below is the code I am using-

<div id="adobe-dc-view" style="width: 800px; box-shadow: 1px 1px 10px 1px #dadada;"></div>
<script type="text/javascript" src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
  <script type="text/javascript">
	  /* The PDF embed mode option here */
	  const viewerConfig = {
		  embedMode: "IN_LINE",
		  showLeftHandPanel: true,
		  showAnnotationTools: true,
		  showDownloadPDF: true, 
		  showPrintPDF: true,
		  showPageControls: true
	  };

	  document.addEventListener("adobe_dc_view_sdk.ready", function () {
		  /* Initialize the AdobeDC View object */
		  var adobeDCView = new AdobeDC.View({
			  /* Registered client id */
			  clientId: "<my client id>",
			  /* The div id in which PDF should be rendered */
			  divId: "adobe-dc-view",
		  });

		  /* Invoke the file preview API on Adobe DC View object */
		  adobeDCView.previewFile({
			  /* Pass information on how to access the file */
			  content: {
				  /* Location of file where it is hosted */
				  location: {
					  url: "https://documentcloud.adobe.com/view-sdk-demo/PDFs/Bodea Brochure.pdf",
				  },
			  },
			  /* Pass meta data of file */
			  metaData: {
				  /* file name */
				  fileName: "Bodea Brochure.pdf"
			  }
		  }, viewerConfig);

		  /* Define Save API Handler */
		  var saveApiHandler = function (metaData, content, options) {
			  console.log(metaData, content, options);
			  return new Promise(function (resolve, reject) {
				  /* Dummy implementation of Save API, replace with your business logic */
				  setTimeout(function () {
					  var response = {
						  code: AdobeDC.View.Enum.ApiResponseCode.SUCCESS,
						  data: {
							  metaData: Object.assign(metaData, { updatedAt: new Date().getTime() })
						  },
					  };
					  resolve(response);
				  }, 2000);
			  });
		  };

		  adobeDCView.registerCallback(
			  AdobeDC.View.Enum.CallbackType.SAVE_API,
			  saveApiHandler,
			  {}
		  );
	  });
  </script>

Any suggestions what I am missing here?
