Can't get text field from settings to render inside a view

How do I get that code? I created it through the UI with MB Settings Page.

Hi,

Here's the field group:

<?php
add_filter( 'rwmb_meta_boxes', 'your_prefix_function_name' );

function your_prefix_function_name( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'          => __( 'Site settings - Texts', 'your-text-domain' ),
        'id'             => 'site-settings-texts',
        'settings_pages' => ['site-configuration'],
        'tab'            => 'tab3',
        'fields'         => [
            [
                'name'              => __( 'Maps not available', 'your-text-domain' ),
                'id'                => $prefix . 'site_settings_texts_maps_not_available',
                'type'              => 'text',
                'label_description' => __( 'Text to show when maps are not available at all', 'your-text-domain' ),
            ],
            [
                'name'              => __( 'Maps for authenticated users only', 'your-text-domain' ),
                'id'                => $prefix . 'site_settings_texts_maps_for_authenticated_users_only',
                'type'              => 'text',
                'label_description' => __( 'Text to show when maps are only available to authenticated users', 'your-text-domain' ),
            ],
            [
                'name'              => __( 'Read more', 'your-text-domain' ),
                'id'                => $prefix . 'site_settings_texts_read_more',
                'type'              => 'text',
                'label_description' => __( 'Button or link text to click to more details', 'your-text-domain' ),
            ],
            [
                'name'              => __( 'Advanced filters', 'your-text-domain' ),
                'id'                => $prefix . 'site_settings_texts_advanced_filters',
                'type'              => 'text',
                'label_description' => __( 'Label for "Advanced filters"', 'your-text-domain' ),
            ],
        ],
    ];

    return $meta_boxes;
}

Here's the settings page:

<?php
add_filter( 'mb_settings_pages', 'your_prefix_function_name' );

function your_prefix_function_name( $settings_pages ) {
	$settings_pages[] = [
        'menu_title' => __( 'Site configuration', 'your-text-domain' ),
        'id'         => 'site-configuration',
        'position'   => 80,
        'style'      => 'no-boxes',
        'columns'    => 1,
        'tabs'       => [
            'tab1' => 'General',
            'tab2' => 'Maps',
            'tab3' => 'Texts',
        ],
        'tab_style'  => 'left',
        'icon_url'   => 'dashicons-admin-generic',
    ];

	return $settings_pages;
}
