Delete Button Not Working After Trial Period

After the test period, the delete button does not respond. Is there any way to stop a specific application?
I would like to understand whether this behavior is intentional or if there is a mechanism to halt the application in this scenario.

Start by reproducing the delete-button behavior after an application enters the trial-period state, then trace the button's frontend flow and any related application-stop handling. Done means determining whether the behavior is intentional and either restoring deletion or documenting the supported mechanism for stopping a specific application.
