How can we add wpform to custom theme-CodePudding

I create custom theme and I am trying to create a contact form using wpform but for some reasons the form doesn't show on my page

here is a code from the custom theme

<?php 
    /* Template Name: CallUS*/
    get_header();?>

<section>
      <div >
        <h1>
          call us
        </h1>
        <img
          
          src="<?php bloginfo('template_directory');?>/images/---1113.png"
          alt=""
          data-image-width="800"
          data-image-height="972"
        />
      </div>
</section>
<?php get_footer();?>

Way 02: If you go to the WPForms from the menu then you can see the shortcode column on each row. it will be like [wpforms id="123"]

Copy your design shortcode from there and use that directly into your file like below:

<?php 
    /* Template Name: CallUS*/
    get_header();?>

<section>
      <div >
        <h1>
          call us
        </h1>
        <img
          
          src="<?php bloginfo('template_directory');?>/images/---1113.png"
          alt=""
          data-image-width="800"
          data-image-height="972"
        />
        <?php echo do_shortcode('[wpforms id="3306"]');?>
      </div>
</section>
<?php get_footer();?>
