You cannot really hide it. The launch has to be public to warn airplanes and ships so they can avoid the area. And once the launch is public, such a failure is quite evident to anyone who was interested in following it, so you might has well publish the news instead of trying to hide the unhidable.
Seriously, I tried Gemini for a while but it is mostly useless. It can it open my apps, cannot control Home Assistant, cannot send a message to someone.
