How to mimic create action?

protected function getFormActions(): array
{
    return array_merge(
        [
            Action::make('Save as draft')
                ->action('saveAsDraft')
        ],
        parent::getFormActions()
    );
}

public function saveAsDraft($data) {
    $data = $this->form->getRawState();
    $data["status_project"] = ProjectStatus::DRAFT;
    static::getModel()::create($data);
}
