UPDATE: How to make CKEditor5 (D10) like the WYSIWYG CKEditor (D7)
After upgrade the Drupal core from Drupal 7 to 10, some users may need to use many editor tools that look like WYSIWYG with CKEditor. However, CKEditor 5 only provides a few tools.
Developers must install CKEditor5 plugins to serve their users.
Required CKEditor5 Plugins:

To create templates, copy the template file to a new location, edit the content in the new file, and then update the path to the template within Text formats and editors.
