Huawei P20pro] How can I disable pop-up alerts?

I constantly get these pop-ups at the top of the screen with my content, previewing the content.

Does anyone know how I can disable this for all apps?

So I do not want the notifications in the pulldown menu to be gone, just do not want this preview to appear on the screen.

It is a Huawei P20 Pro with Android 9 and EMUI 9.0.0

With Whatsapp you can deposit this in the settings.

I mean more generally, since I have already deactivated it with whatsapp and still get notifications. I assume that the system itself presents every notification as a pop-up. Nevertheless, thanks for the tip
