Vaadin Avatar-Group

I am trying to use the standard avatar group component of vaadin:
https://vaadin.com/docs/latest/components/avatar/styling

I added this component to a HorizontalLayout. I am now trying to make the avatarbubble justify:center but I fail to do so. I managed to access the vaadin-avatar-group html tag with my css styling and made it yellow. But i can’t seem to acces the div element with the id(container), which seems to be responsible for the justify-property.

See also the screenshot attached.
Could anybody help me with that?
