Video is not the main content of the page

Hello everyone, i am not able to fix this issue in the Search Console Video is not the main content of the page but actually it is!

When you enter in my product page the first thing that appears is the video it self! (hosted on imgur platform)

I even added additional Schema video tags but that seems is useless.

here is the code i am using:

P.S: $image4 variable sometimes can contain video link or image link.

<?php if (!empty($image4)): ?>
    <div class="swiper-slide">
        <div class="dz-media" itemscope itemtype="http://schema.org/VideoObject">
            <?php
            if (pathinfo($image4, PATHINFO_EXTENSION) === 'mp4') {
                // Display a video if the link points to an MP4 file
                echo '<meta itemprop="thumbnailUrl" content="' . $image1 . '">';
                echo '<meta itemprop="contentUrl" content="' . $image4 . '">';
                echo '<video controls width="100%" height="auto" poster="' . $image1 . '" itemprop="video">';
                echo '<source src="' . $image4 . '" type="video/mp4">';
                echo 'Your browser does not support the video tag.';
                echo '</video>';
            } elseif (in_array(pathinfo($image4, PATHINFO_EXTENSION), array('png', 'jpg', 'jpeg'))) {
                // Display an image if the link points to a PNG, JPG, or JPEG file
                echo '<img src="' . $image4 . '" alt="' . $product_tags . '">';
            }
            ?>
            <meta itemprop="name" content="<?php echo htmlspecialchars($product_name); ?>">
            <meta itemprop="description" content="<?php echo htmlspecialchars($product_description); ?>">
            <meta itemprop="uploadDate" content="<?php echo date('c', strtotime($upload_date)); ?>">
        </div>
    </div>
<?php endif; ?>
