Thank you for your reply and for confirming this. The fact that there are no public APIs for blocking screenshots was actually our starting point, and this was made clear at the beginning of the original post. I had to reply to you with a new post below the old one.

Thank you for the reply and for the confirmation. The acknowledgment of the absence of public APIs for screenshot prevention was actually the starting premise of our request, which we had explicitly stated in the opening of the original post. We will of course proceed with filing the enhancement request via Feedback Assistant as suggested, and we will post the FB number here as soon as it is available so it can be routed to the appropriate team.
