Testing: How to call a table action within a relation manager?

// CountriesRelationManager.php

public function table(Table $table): Table
{
    return $table
        // ...
        ->actions([
            // ...
            Action::make('moveUp')
                ->action(function (Action $action) {
                    $action->getRecord()->moveOrderUp();
                }),
        ]);
        // ...
}

it('allows moves sort order up on assicated children', function () {
    $continent = Continent::factory()
        ->hasCountries(2)
        ->create();

    livewire(CountriesRelationManager::class, [
        'pageClass' => EditContinent::class,
        'ownerRecord' => $continent,
    ])
    ->callTableColumnAction('moveUp', $continent->countries->last()->id);

    expect($continent->countries->first()->fresh()->sort_order)->toBe(2);
    expect($continent->countries->last()->fresh()->sort_order)->toBe(1);
});
