Now the messages appear in the list view. However, the notification count does not change even after I read the messages

that's another issue see #26921 and should be managed in a separate PR

Please check the image below. The referred issue is different from this.

I agree with @thite-amol and modify my test

looks like getitems will get all items pertaining to the user whatever the state of the message. It works in the Messages manager because we have filters, but not for the module

I get it to work by using the query we had in J3
