it('shows the create form for a new contract', function(): void {
    $client = Client::query()->first();

    livewire(ContractsRelationManager::class, [
        'ownerRecord' => $client,
        'pageClass' => EditClient::class,
    ])->assertSuccessful()
    ->assertTableHeaderActionsExistInOrder(['create'])
    ->mountAction('create')
