How to display CPT with a shortcord

I made this CPT Review

	$labels = array(

		'name'                  => _x( 'Review', 'Post Type General Name', 'twentythirteen-child' ),

		'singular_name'         => _x( 'Review', 'Post Type Singular Name', 'twentythirteen-child' ),

		'add_new'               => __( 'Add New', 'twentythirteen-child' ),

		'new_item'              => __( 'New Review', 'twentythirteen-child' ),

		'edit_item'             => __( 'Edit Review', 'twentythirteen-child' ),

		'update_item'           => __( 'Update Review', 'twentythirteen-child' ),

		'items_list'            => __( 'Slider list', 'twentythirteen-child' ),

		'items_list_navigation' => __( 'Slider list navigation', 'twentythirteen-child' ),

		'filter_items_list'     => __( 'Filter items list', 'twentythirteen-child' ),

	);

	$args = array(
		'label'                 => __( 'Review', 'twentythirteen-child' ),
		'description'           => __( 'Review Description', 'twentythirteen-child' ),
		'labels'                => $labels,
		'supports'              => array( 'title','revisions', 'excerpt', 'editor' ),
		'hierarchical'          => false,
		'public'                => true,
		'show_ui'               => true,
		'show_in_menu'          => true,
		'menu_position'         => 26,
		'show_in_admin_bar'     => true,

		'publicly_queryable'    => true,
		'capability_type'       => 'page',
		'menu_icon'				=> 'dashicons-welcome-view-site',
		'rewrite' => array( 'with_front'=> false,'slug' => 'review' ),
	);

	register_post_type( 'review', $args );

After that I made a plugin to display form at the frontend.

Now I don’t know How to show Things of The CPT to front end.

I made this code so far but no clue what to do ahead.

function display_testimonials(){

$temp = '<div class="owl-carousel testi-slider">
						<div class="container">
							<div class="row">
								<div class="col-md-4">
									<div class="testimonial text-center">
										<h3>Just Perfect!</h3>
										<div class="separator"></div>
										<div class="testimonial-body">
											<blockquote>
												<p>Sed ut perspiciatis unde omnis iste natu error sit voluptatem accusan tium dolore laud antium, totam rem dolor sit amet tristique pulvinar, turpis arcu rutrum nunc, ac laoreet turpis augue a justo.</p>
											</blockquote>
											<div class="testimonial-info-1">- Jane Doe</div>
											
										</div>
									</div>
								</div>
							</div>
						</div>
						<div class="container">
							<div class="row">
								<div class="col-md-4">
									<div class="testimonial text-center">
										<h3>Just Perfect!</h3>
										<div class="separator"></div>
										<div class="testimonial-body">
											<blockquote>
												<p>Sed ut perspiciatis unde omnis iste natu error sit voluptatem accusan tium dolore laud antium, totam rem dolor sit amet tristique pulvinar, turpis arcu rutrum nunc, ac laoreet turpis augue a justo.</p>
											</blockquote>
											<div class="testimonial-info-1">- Jane Doe</div>
											
										</div>
									</div>
								</div>
							</div>
						</div>
					
</div>';

		return $temp;
}

add_shortcode('DT','display_testimonials');

Kindly please give your advice and help.
