'ion-fab-button' is not a known element

Hi there,

I’m trying to implement a ion-fab-button but however I give it a try it does not work properly. As mentioned in the title it is not a known element and I can’t find a solution for that.

I’m working with VS Code. Would be nice if someone can help me out!

<ion-content>
  <ion-fab>
    <ion-fab-button>
      
    </ion-fab-button>
  </ion-fab>
</ion-content>

This here is my ionic info:

Ionic:

Ionic CLI : 5.2.4 (C:\Users\User\AppData\Roaming\npm\node_modules\ionic)
