Steps to reproduce the issue

Create a new user group with permission core.manage on com_messages, add user to this group. Create a content transition (workflow) that sends a notification to this new group.
(likely possible to replicate multiple ways)

Expected result

A new message sent to a user (in a user group that is not super user), when an article transition is performed.

Actual result

No message is created/emailed to the user in question.

System information (as much as possible)

Joomla 4.3.3

Additional comments

This looks like a typo in this file: plugins/workflow/notification/notification.php on line 202, "com_message" instead of "com_messages" in the authorisation condition.
