HeaderActions in Component (not Resource)

Ciao helpful Filament Community

I am trying to add a headeraction to a table.
This works fine in a class that extends Resource (first and second screenshot).

But in another project i have a different structure and i want to set a headeraction in a Class that extends Component (third screenshot).
This headeraction inside a component class is shown in a strange way and i cant set a label or color.

Also my npm run dev is showing a warning which could be a hint for the problem but i dont know:
"(node:13620) Warning: An error event has already been emitted on the socket. Please use the destroy method on the socket while handling a 'clientError' event.
(Use node --trace-warnings ... to show where the warning was created)"

Can someone tell me why i cant use headeractions inside a Class that extends Component instead of Resource?
And maybe tell me how the correct way would be?

Thanks alot in advance
