CKEditor 5 Limit character count script

Description

We have a textarea which uses CKEditor 5, but we need to limit the character count of the entry to a predefined limit.
The code already uses the WordCount plugin and an example will be provided, but we require the code to stop allowing the user to enter any more text into the textarea box once the limit has been met.
Key requirements:
- Must be in JavaScript/HTML with clear comments- The character limits should be editable and custom to multiple iterations of the code being used- Must use the example code (provided to successful developer) with basic editor functions- Must show the character count
An example can be seen at https://ckeditor.com/docs/ckeditor5/latest/features/word-count.html#reacting-to-updates
