Hide-shortcode based on iframes.

Right now, i use this code to redirect user to google in this example case, if this site is not visited via a iframe and if he is not from those domains entered: <?php add_action( 'wp_head', function () { ?> <script> const allowedDomains = ['[login to view URL]', '[login to view URL]','[login to view URL]']; if ([login to view URL]([login to view URL]('/')[2]) === -1) { [login to view URL] = '[login to view URL]'; } </script> <?php } );?> But I would love to have a shortcode to load content (for example mycred-shortcodes) based on iframe parent. e.g.: Hello Only show [show_if_iframe domains="[login to view URL], [login to view URL], [login to view URL]"]CONTENT[/show_if_iframe] based on iframe. Please make sure, it's not a "display:none", but a function, to do not load those content. as i know from the [hide for="logged"] and the [mycred_show_if]-Shortcodes. Here content is not hidden. It's not loaded, wenn those conditions do not match. If user uses iframes and the domains, this shall be loaded based on example above: -Hello Only show CONTENT based on iframe. This shall be loaded, when user do not load this site via i frame -Hello Only show based on iframe. (CONTENT is missing in will not be loaded)
