Creating Conditional Fields in Elementor Custom Widget

How are conditional fields or field groups created in Elementor? I’ve not found anything in the documentation regarding conditional fields for widget development. A simple example of what I’d like to do is the following:

I have a dropdown:

    // Select Control     $  this->add_control(         'dropdown_Example',         [             'label' => __('Dropdown Example', 'vs'),             'type' => \Elementor\Controls_Manager::SELECT,             'options' => [                 'default' => __('Default', 'vs'),                 'yes' => __('Yes', 'vs'),                 'no' => __('No', 'vs'),             ],             'default' => 'default',         ]     ); 

If the answer in the dropdown is yes, then show text field 1:

    // Text 1     $  this->add_control(         'text1',         [             'label' => __('Text1', 'vs'),             'type' => Controls_Manager::TEXT,         ]     ); 

Else, show text field 2:

    // Text 2     $  this->add_control(         'text2',         [             'label' => __('Text2', 'vs'),             'type' => Controls_Manager::TEXT,         ]     );
