Show in YouTube videos?

I have seen in many videos on YouTube flashes / graphics on which, for example, subscribe / activate bell / Twitch: … Stands. Do these graphics have a special name?

Call it what you want…
You can just say "fade in", maybe if that's equivalent to "Lower Third"

Especially on YouTube or in general in the Web video area but also the English name "Overlay" is common.

Overlay or overlay.

The nature of these overlays is then referred to as a call-to-action, that is, as a call to perform an action, such as a call. To subscribe somebody.

Fades with names are called the belly band or insert.
