I have created a preview button, I use JS to create this button. But I have issue when I click on the button, it says that :
admin.php?page=wooster-partner:1331
GET http://wordpressoceane.local/wp-admin/get_preview_link.php?post_id=11130 404 (Not Found)
admin.php?page=wooster-partner:1331
GET http://wordpressoceane.local/wp-admin/get_preview_link.php?post_id=11131 404 (Not Found)

For each button , I have the Id of the page created, so it seems to well retrieve the id of the page when I click on the preview button. But it will not redirect to the page.

First I created the ajax to create a row and add the element

  const actionsCell = document.createElement('td');
        actionsCell.classList.add('actions'); // Add a class for styling


        const viewButton = document.createElement('button');
        viewButton.classList.add('viewBtn');
        viewButton.innerHTML = '<i class="fas fa-eye fa-lg"></i>';
        viewButton.addEventListener('click', () => {
            // Assuming data.id contains your post ID
            const postId = data.id; // Replace data.id with your actual post ID variable

            // Make an AJAX request to get the preview link
            fetch('get_preview_link.php?post_id=' + postId)
                .then(response => response.text())
                .then(previewUrl => {
                    // Redirect to the preview page of the post
                    window.location.href = previewUrl;
                });
        });

Then in the back , I added a function to retrieve the id

     function get_preview_link_callback() {
        // Check if the post ID is set in the AJAX request
        if (isset($_GET['post_id'])) {
            // Get the post ID from the AJAX request
            $post_id = $_GET['post_id'];

            // Get the preview link for the post
            $preview_url = get_preview_post_link($post_id);

            // Send the preview URL as the AJAX response
            echo $preview_url;
        }

        // Always remember to terminate the script
        wp_die();
    }
