New "Class" button :: cannot be clicked a second time. How to get a callback from a second click?

Question

Classmates

When using the new "Class" button, I encountered such a problem:
if the user has already clicked on the "Class" button before, then he can no longer click again. Therefore, getting a callback from a successful button press will not work either.
Please add one of the proposed options to this widget:
- add a postmessage when the "Class" button is clicked again (as it was done on the first click)
- add a postmessage when loading the widget, which indicates whether the user clicked the class before
Or please tell me how this can be solved by existing tools. Picked the initializing postmessage of the type "ok_setStyle$..." - it does not contain information about the previously pressed button.
