The ads shows that once you connect the app to the casino, it can cancel the game and cash out for you or can make the aviator to continue driving until you are ready to cash out your profit. Don't fall for this. I have not seen this kind of ads anywhere except on telegram and I think it's just on telegram they have the freedom to post it because other sites will not allow it, except a scam site too.
Even on Telegram, if someone enters without permission, it means there's a setting you haven't set. Whether you set it or not, the quickest option is to simply not click on anything. It could be hacked, and the app might send something we don't know, allowing us to easily access important information on our phone.
I've been there too, but I never open unimportant links, so I block and delete them permanently. It's like having a credit card at a bank. Our number is spread everywhere. When we confirm, we're a company from the platform you choose. Nothing private is leaked.
