Displaying filters above or below the table content

I cant get to work this. In my CenterResource.php i add the methos:

protected function getTableFiltersLayout(): ?string
    {
        return Layout::BelowContent;
    }

protected function getTableFiltersLayout(): ?string
    {
        return Layout::BelowContent;
    }

protected function getTableFiltersLayout(): ?string
    {
        return Layout::BelowContent;
    }

protected function getTableFiltersLayout(): ?string
    {
        return Layout::BelowContent;
    }

i also added:

use Filament\Tables\Filters\Layout;

use Filament\Tables\Filters\Layout;

use Filament\Tables\Filters\Layout;

use Filament\Tables\Filters\Layout;

`

But the method is not being called. It shows in PHPStorm as unused element.

From where do i have to call the method please?
