How to add custom button to backend order table in Woocommerce?

Watson

When the user clicks on the Woocommerce / Orders menu at the backend, all available order information will be shown. There are several fields/columns in order to this table (such as order, ship to, date, total, actions).
There are two buttons under the action field (order status and view). I want to add another button to the field below. Is there any code available that can be applied to functions.php to solve this problem.

For adding add custom button to backend order table you can use this code

add_action( 'woocommerce_admin_order_actions_end', 'add_content_to_wcactions_column' );
function add_content_to_wcactions_column() {

    // create some tooltip text to show on hover
    $tooltip = __('Some tooltip text here.', 'textdomain');

    // create a button label
    $label = __('Label', 'textdomain');

    echo '<a class="button tips custom-class" href="#" data-tip="'.$tooltip.'">'.$label.'</a>';
}
