Event Calendar and GP Element Page Hero

I have a similar problem. I am evaluating The Event Calendar on my test system and tried to make a GPP Page Hero for a single event. I made a Page Hero, (Block Element, Page Hero, hook before_content, priority 10). I could select the category (events) in the selection area. Above the single event a white space appears, but not the Page Hero with a featured image and a title. The same block does work on regular posts.

TEC posts have a title and a featured image in the wp-posts database. TEC ha a template overriding system that can be place in the wp-content/themes/generatepress/tribe folder (or in a child-theme).

There is a single-event.php file:

<?php
/**
 * Single Event Template
 * A single event. This displays the event title, description, meta, and
 * optionally, the Google map for the event.
 *
 * Override this template in your own theme by creating a file at [your-theme]/tribe-events/single-event.php
 *
 * @package TribeEventsCalendar
 * @version 4.6.19
 *
 */

if ( ! defined( 'ABSPATH' ) ) {
	die( '-1' );
}

$events_label_singular = tribe_get_event_label_singular();
$events_label_plural   = tribe_get_event_label_plural();

$event_id = Tribe__Events__Main::postIdHelper( get_the_ID() );

/**
 * Allows filtering of the event ID.
 *
 * @since 6.0.1
 *
 * @param int $event_id
 */
$event_id = apply_filters( 'tec_events_single_event_id', $event_id );

/**
 * Allows filtering of the single event template title classes.
 *
 * @since 5.8.0
 *
 * @param array  $title_classes List of classes to create the class string from.
 * @param string $event_id The ID of the displayed event.
 */
$title_classes = apply_filters( 'tribe_events_single_event_title_classes', [ 'tribe-events-single-event-title' ], $event_id );
$title_classes = implode( ' ', tribe_get_classes( $title_classes ) );

/**
 * Allows filtering of the single event template title before HTML.
 *
 * @since 5.8.0
 *
 * @param string $before HTML string to display before the title text.
 * @param string $event_id The ID of the displayed event.
 */
$before = apply_filters( 'tribe_events_single_event_title_html_before', '<h1 class="' . $title_classes . '">', $event_id );

/**
 * Allows filtering of the single event template title after HTML.
 *
 * @since 5.8.0
 *
 * @param string $after HTML string to display after the title text.
 * @param string $event_id The ID of the displayed event.
 */
$after = apply_filters( 'tribe_events_single_event_title_html_after', '</h1>', $event_id );

/**
 * Allows filtering of the single event template title HTML.
 *
 * @since 5.8.0
 *
 * @param string $after HTML string to display. Return an empty string to not display the title.
 * @param string $event_id The ID of the displayed event.
 */
$title = apply_filters( 'tribe_events_single_event_title_html', the_title( $before, $after, false ), $event_id );
$cost  = tribe_get_formatted_cost( $event_id );

	<!-- #tribe-events-footer -->

</div><!-- #tribe-events-content -->

A single event has 7 templates: back-link, title, content, footer, notices, recurring-description, comments). Their content is rather limited. The title template is:
<?php the_title( '<h1 class="tribe-events-single-event-title">', '</h1>' );

The back-link-template (which is above the title):

<?php
$label = esc_html_x( 'All %s', '%s Events plural label', 'the-events-calendar' );
$events_label_plural = tribe_get_event_label_plural();
?>
<p class="tribe-events-back">
	<a href="<?php echo esc_url( tribe_get_events_link() ); ?>">
		&laquo; <?php printf( $label, $events_label_plural ); ?>
	</a>
</p>

Content-template:

<?php $event_id = $this->get( 'post_id' ); ?>
<div id="post-<?php echo absint( $event_id ); ?>" <?php post_class(); ?>>
	<?php tribe_the_content( null, false, $event_id ); ?>
</div>

Is this info OK?

Is there a way getting the GPP Page Hero working on a single event of the Event Calendar?

Thanks !
