Add info about difference between this module and ckeditor_mentions

Hi @sickness29 Thank you for the feedback. The https://www.drupal.org/project/ckeditor_mentions → , was only compatible with CKEditor 4 at the time. However, I am pleased to note that the CKEditor Mentions module has recently been updated to also support CKEditor 5. I will update the 'About' section according to the proposed resolution.

1-ckeditor_mentions →
+The mentioned entity is in link format that links to its own page instead of string format by default.
+It works well with token module with satisfactory coverage. So you can easily create a notification system or integrate it with supporting modules like message → or ckeditor_mentions_notifications → .
--You cannot restrict or filter the entity type & role permission.
- It doesn't support all types. You can only mention user & node.

2-CKEditor5 Mentions →
+Seems to support all kinds of entities You can mention taxonomy term. Seems to support all kinds of entities (I have not tested other entity types except node and taxonomy)
It would be nice if there was a multiple choice option during selection.
+ Permissions to mention/to be mentioned.
+Notification system.Your need ckeditor5_premium_features → .
-The token scope is not as wide as the ckeditor_mentions.

Both modules work within the mentioned framework.
Both modules do not support specific node(entity) restriction. Customization required.

Currently, first module is more suitable for me, as I think its integration with the token scope is more flexible.

But with the support of ckeditor5_premium_features → , you can try different options with the second module. It comes with many different features (with registeration API). It has own ecosystem.
