plugins - Office.js | Comments not showing immediately after adding through Office.js - Stack Overflow

I am building a word add-in, one of the main functions is that it can insert comments in specific parts of the document. The whole thing works well when used in locally installed Word, but as soon as we shift things to online web-based Word, and try to add comments programmatically, the following things happen on the UI:

• The place where we try to add comments gets a comment logo
• In the comments tab, the text that says "There are no comments in this document" disappears.
• If the document is shared, all the collaborators get an email notification about the comment being added.

But, as soon as I refresh the whole page by clicking the refresh button on my browser, magically all the comments start showing up.

Here's my implementation:

async function addCommentsToDoc(targetString: string, commentText: string) {

// Calling run method from Word package, to initialize the context
const result = Word.run(async (context) => {
  await context.sync();
  // Handling Word's 255 character search limit
  if (targetString.length >= 255) {
    targetString = targetString.slice(0, 250);
  }

  // Cleaning the location
  targetString =  targetString.trim()

  // Getting the complete content of the current open document or content
  const body = context.document.body;

  // Using the native .search() method to search within a string.
  const searchResults = body.search(
    targetString,
    {
      matchCase: false,
      matchWholeWord: false,
      ignoreSpace: true,
      ignorePunct: false,
      matchPrefix: false,
      matchSuffix: false,
      matchWildcards: false
    }
  );
  
  // Loading the searched properties from the document
  context.load(searchResults, "text");
  await context.sync();

  if (searchResults.items.length > 0) {
    //Skip the comments who's length is 0
    if (commentText.length == 0) {
      return;
    }

    // Adding the comment to the target string
    const comment: Word.Comment = searchResults.items[0].insertComment(commentText);
    comment.track();
    comment.load(
      "id, content, authorName, contentRange, resolved, replies"
    );
    await context.sync();

    const range = comment.getRange();
    range.select("Start");
    await context.sync();

    return true;
  } else {
    return false;
  }
});

}
