How to search a single field of 3 tables with JOIN using Respect Relational?

Question

I’m starting to use the framework Respect\Relational and I was just trying to get the names of the chart templates that belong to the id 1 business line, but all the forms I tried always returns all the columns. What would be the right way to do this using the framework Respect\Relational?

This is the image of the necessary bank part:

These were some attempts that also did not work:

$this->mapper->letterTemplatesNames = Filtered::by('name')->letter_templates();

$this->mapper->hiddenLetterTemplatesBusinessLines = 
      Filtered::letter_templates_business_lines();

$response = $this->mapper->letter_templates
      ->letter_templates_business_lines
      ->business_lines[(int) $value]
      ->fetchAll(Sql::orderBy('letter_templates.name')
      ->asc()
      ->limit($limit));

$response = $this->mapper->letter_templates
      ->letter_templates_business_lines(
          array('business_lines_id' => (int) $value))
      ->fetchAll(Sql::orderBy('letter_templates.name')
      ->asc()
      ->limit($limit));

$response = $this->mapper->letterTemplatesNames
      ->letter_templates_business_lines
      ->business_lines[(int) $value]
      ->fetchAll(Sql::orderBy('letter_templates.name')
      ->asc()
      ->limit($limit));

$response = $this->mapper
      ->hiddenLetterTemplatesBusinessLines(
        array('business_lines_id' => (int) $value))
      ->letterTemplatesNames
      ->fetchAll(Sql::orderBy('letter_templates.name')
      ->asc()
      ->limit($limit));
