Can we remove case sensitive on annotation users

Consider a user with name - firstname and we import a file with comments added by firstname and another comment added by Firstname(F is capital here).
The edit permission is gone for the second comment which is added by Firstname.
But these 2 are same users with some case difference.

Is there any way to make the comment users as case insensitive?

Hello priya1234sony,

There’s an API setPermissionCheckCallback , documentation here.

const {annotationManager} = instance.Core;
annotationManager.setPermissionCheckCallback((author) => {
      const customPermission = author.toLowerCase() === annotationManager.getCurrentUser().toLowerCase();
      return customPermission;

Hope this helps!
