Draft.js Mention Plugin is not working after rendering contentState to the editor

I am using mentions with the draft.js (like this @yourname) and sending to the database to save and fetching it to render on the web page but things are not working as expected.

On Saving to the database ->

const contentState = editorState.getCurrentContent();
const currentStateData = convertToRaw(contentState);
const richStringifyValue = JSON.stringify(currentStateData);
// sending richStringifyValue to save in Mongo DB

On Fetch and set in editor ->

const [editorState, setEditorState] = React.useState(() => EditorState.createEmpty());
const parsedData = JSON.parse(post.contentStyled);
const fromRawData = convertFromRaw(parsedData );
EditorState.createWithContent(fromRawData);


// here is the view rendered part -
   <Editor 
     readOnly={true}
     editorState={editorState}
   />

But after setting in editor (after the data fetched from API) my mentions (@... @... @...) lost the CSS. What should we do?

On Using Edit ->

On fetch and setting again in Editor ->

I don't know why is that happening, please help to resolve this issue!

You should do the following:

const [editorState, setEditorState] = React.useState(() => {
  const parsedData = JSON.parse(post.contentStyled);
  const fromRawData = convertFromRaw(parsedData );
  return EditorState.createWithContent(fromRawData);
});

// ...
   <Editor 
     readOnly={true}
     editorState={editorState}
   />

If you override the editorState with a new created state you are removing all the decorators which were added by the plugins.
