Showing Metabox for only certain template page

Question

I am trying to show a certain metabox only on a certain template. I have tried putting this code in my functions.php file:

    add_filter('rwmb_meta_boxes', 'main_page_register_meta_boxes' );

    function main_page_register_meta_boxes( $meta_boxes ) {
        $prefix = '';
        remove_post_type_support('page', 'editor');
    
        $meta_boxes[] = [
            'title'   => esc_html__( 'Header', 'Header' ),
            'id'      => 'Header_section_1',
            'post_types' => ['page'],
            'context'    => 'normal',
            'include' => array(
                'template' => array( 'content-mainPage.php' ),
            ),
            'fields'  => [
                [
                    'type'  => 'text',
                    'name'  => esc_html__( 'title', 'title' ),
                    'id'    => $prefix . 'title',
                    
                ],
                [
                    'type'  => 'wysiwyg',
                    'name'  => esc_html__( 'Description', 'Description' ),
                    'id'    => $prefix . 'Description',
                    
                ],
            ],
        ];
    
       
    
        return $meta_boxes;
    }

I found a solution that adds a display condition for a specific page template but it doesn't work in my case

'include' => array(
                'template' => array( 'content-mainPage.php' ),
            ),

The still created metabox is displayed when editing each page.

Does anyone know how to create a metabox that will be assigned to a specific Wordpress page template?
