Track the moment of closing some tab in UniPageControl

[artem_niko]

Good afternoon!

Does UniPageControl have some kind of property, event, with which it would be possible to track the moment of closing of some tab?
For example, if there are 3 tabs on UniPageControl now, then if some tab is closed, then execute the code.
I don't mean the onClose event in UniTabSheet. I need to track, at the UniPageControl level, the moment that some tab closed.

  ShowToast('+++');

The code on this link is good, by the way, yes, it will be useful to me later now.
But!
My question is not about the tab closing event, namely when the tab was already closed, after it was closed.
I need to unload the DLL package simply.
If I put the upload code in the tab closing event, the application freezes, because the tab is created dynamically and destroyed by clicking on the button.

How to execute the code exactly after closing the tab?

Sorry, your case is not clear to me.
