Condicional metabox

Hello.
I am trying to add a metabox depending on the choice of another metabox.

In the first metabox I choose the category of the custom post and depending on the choice I need to specify metabox.

In the following code it should show the metabox “skulpt_metabox” but I can’t get it to work.

Thank you very much in advance.

/**
 * Agregar un metabox valoración funcional para elegir el tipo de valoracion
 **/

add_action( 'cmb2_init', 'tv_register_metabox' );
/**
 * Hook in and add a demo metabox. Can only happen on the 'cmb2_init' hook.
 */
function tv_register_metabox() {

	// Start with an underscore to hide fields from custom fields list.
	$prefix = 'tv_';

	/**
	 * Sample metabox to demonstrate the different conditions you can set.
	 */
	$cmb_demo = new_cmb2_box( array(
		'id'            => $prefix . 'metabox',
		'title'         => 'Tipo de valoración funcional',
		'object_types'  => array( 'valoracion-funcional' ), // Post type.
	) );

	/**
	 * Group fields works the same, except ids only need
	 * to be unique to the group. Prefix is not needed.
	 *
	 * The parent field's id needs to be passed as the first argument.
	 */

	$cmb_demo->add_field( array(
		'name'     => esc_html__( 'Tipo de valoración', 'cmb2' ),
		'desc'     => esc_html__( 'Elegir una opción', 'cmb2' ),
		'id'       => 'taxonomy_radio',
		'type'     => 'taxonomy_select_hierarchical', // Or <code>taxonomy_radio_inline</code>/<code>taxonomy_radio_hierarchical</code>
		'taxonomy' => 'tipo-valoracion-funcional', // Taxonomy Slug
		// 'inline'  => true, // Toggles display to inline
		// Optionally override the args sent to the WordPress get_terms function.
		'query_args' => array(
			// 'orderby' => 'slug',
			// 'hide_empty' => true,
		),
	) );
