How to put custom fonts in combobox in JavaFX?

Question

Java

There is a label with text and a combobox in the application. When I click on the combobox, a list of fonts pops up. When you click on a font, the font of the label text changes to the selected one. At the moment, my combobox is working fine, but only fonts that are installed in the system (WIndows / fonts) are displayed there, but I need only fonts from the folder located in the program folder to be displayed in the combobox.

How to display my custom fonts in combobox?
If it is not possible to put your custom fonts from the program folder in the combobox, is it possible to change the path to the system folder with fonts?

@FXML  private ComboBox<Font> fontSelector;
@FXML  private Label fontLabel;

//get font family and size 
  private static Font getFont(Font font, Integer size) {
    return Font.font(font == null ? null : font.getFamily(), size == null ? -1d : size.doubleValue());
  }

//add font families to combboox
    fontSelector.getItems().addAll(Font.getFamilies().stream().map(name -> Font.font(name, 14)).toArray(Font[]::new));

// bind font based on size/family
    fontLabel.fontProperty()
            .bind(Bindings.createObjectBinding(() -> getFont(fontSelector.getValue(), size.getValue()),
                    fontSelector.valueProperty(), size.valueProperty()));

//display and render font families looks in combobox
    class FontListCell extends ListCell<Font> {
      @Override
      public void updateItem(Font item, boolean empty) {
        super.updateItem(item, empty);
        if (item != null) {
          setText(item.getFamily());
          setFont(item);
        } else {
          setText("");
          setFont(Font.font(12));
        }
      }
    }

    fontSelector.setCellFactory(lv -> new FontListCell());
    fontSelector.setButtonCell(new FontListCell());
