How to change theme layout via url parameter ?

Hello

i have create a customizer option for sidebar position. My question is how can i show sidebar position via url parameter like my sidebar position is selected as a right sidebar as a default but if i change url like ‘mysite.com/?sidebar_position=left-sidebar‘ i need to see sidebar to located on left side without changing option from customizer.

Thanks

Customizer option code is here

// Sidebar Position

$wp_customize->add_section( 'sidebar_position', array(
        'title' => __('Sidebbar Position', 'my_textdomain'),
        'description' => __('Select Sidebar Position.', 'my_textdomain'),
        'priority' => '900',
	) );

$wp_customize->add_setting( 'sidebar_position_option', array(
      'default' => 'right-sidebar',
      'type' => 'theme_mod',
	'sanitize_callback' => 'candour_sanitize_sidebar_placement',
) );

$wp_customize->add_control( 'sidebar_position_option', array(
    'label' => __('Display Sidebar on Left or Right', 'my_textdomain'),
    'section' => 'sidebar_position',
    'type' => 'radio',
    'choices' => array(
        'right-sidebar' => __('Right (Default)', 'my_textdomain'),
    	'left-sidebar' => __('Left', 'my_textdomain'),
        ),
) );

function candour_sanitize_sidebar_placement( $input ) {
    $valid = array(
        'right-sidebar' => __('Right (Default)', 'my_textdomain'),
    	'left-sidebar' => __('Left','candour'),
    );

    if ( array_key_exists( $input, $valid ) ) {
        return $input;
    } else {
        return '';
    }
}
