What different Action method `using` and `action` ?

EditAction::make()
    ->using(function (Model $record, array $data): Model {
        $record->update($data);

        return $record;
    })

EditAction::make()
    ->using(function (Model $record, array $data): Model {
        $record->update($data);

        return $record;
    })

Action::make('sendEmail')
    ->form([
        TextInput::make('subject')->required(),
        RichEditor::make('body')->required(),
    ])
    ->action(function (array $data) {
        Mail::to($this->client)
            ->send(new GenericEmail(
                subject: $data['subject'],
                body: $data['body'],
            ));
    })

Action::make('sendEmail')
    ->form([
        TextInput::make('subject')->required(),
        RichEditor::make('body')->required(),
    ])
    ->action(function (array $data) {
        Mail::to($this->client)
            ->send(new GenericEmail(
                subject: $data['subject'],
                body: $data['body'],
            ));
    })
