We do not plan adding another links, it is irrelevant.
You may update in functions.php this line:
"message": "<?php echo osc_esc_html(ckc_param('content_message') <> '' ? ckc_param('content_message') : __('This website uses cookies to ensure you get the best experience on our website.', 'cookie_consent')); ?>",
And add there custom link or custom HTML code, but honestly I have not tested if HTML will be accepted here or not.
