I want to show product categories and not product directly on Dokan store page

I am using Dokan for a Multipurpose store. I have already set up 2 vendors with their individual products. When I click on each vendor, I want to see the categories of products and not the products directly. I need guidance on how to go about it.

Here is the link to the website: https://entertainers.vipclubguest.com/

Thank you.

SO, after contacting the plugin owner, he could not help as the edit I need is out of their support scope. However, he gave me a pointer of where to look and below is the code that is in the file:

<?php

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

$store_user   = dokan()->vendor->get( get_query_var( 'author' ) );
$store_info   = $store_user->get_shop_info();
$map_location = $store_user->get_location();
$layout       = get_theme_mod( 'store_layout', 'left' );

get_header( 'shop' );

if ( function_exists( 'yoast_breadcrumb' ) ) {
    yoast_breadcrumb( '<p id="breadcrumbs">', '</p>' );
}
?>
    <?php do_action( 'woocommerce_before_main_content' ); ?>

    <div class="dokan-store-wrap layout-<?php echo esc_attr( $layout ); ?>">

        <?php if ( 'left' === $layout ) { ?>
            <?php dokan_get_template_part( 'store', 'sidebar', array( 'store_user' => $store_user, 'store_info' => $store_info, 'map_location' => $map_location ) ); ?>
        <?php } ?>

        <div id="dokan-primary" class="dokan-single-store">
            <div id="dokan-content" class="store-page-wrap woocommerce" role="main">

                <?php dokan_get_template_part( 'store-header' ); ?>

                <?php do_action( 'dokan_store_profile_frame_after', $store_user->data, $store_info ); ?>

                <?php if ( have_posts() ) { ?>

                    <div class="seller-items">

                        <?php woocommerce_product_loop_start(); ?>

                            <?php while ( have_posts() ) : the_post(); ?>

                                <?php wc_get_template_part( 'content', 'product' ); ?>

                            <?php endwhile; // end of the loop. ?>

                        <?php woocommerce_product_loop_end(); ?>

                    </div>

                    <?php dokan_content_nav( 'nav-below' ); ?>

                <?php } else { ?>

                    <p class="dokan-info"><?php esc_html_e( 'No products were found of this vendor!', 'dokan-lite' ); ?></p>

                <?php } ?>
            </div>

        </div><!-- .dokan-single-store -->

        <?php if ( 'right' === $layout ) { ?>
            <?php dokan_get_template_part( 'store', 'sidebar', array( 'store_user' => $store_user, 'store_info' => $store_info, 'map_location' => $map_location ) ); ?>
        <?php } ?>

    </div><!-- .dokan-store-wrap -->

    <?php do_action( 'woocommerce_after_main_content' ); ?>

<?php get_footer( 'shop' ); ?>
