Cron Error: No such file or directory

Looking for some guidance around setting up a cron job to run every 15 minutes that sets off a script within the WordPress Plugin Amelia. According to their docs, I need to add the following line to the Cron file: */15 * * * * https://domain.com/wp-admin/admin-ajax.php?action=wpamelia_api&call=/notifications/scheduled/send Now as I'm using CPanel I set up the cronjob using the gui so it looks something like this. Swapping https://domain.com for the actual domain.: I've added quotes to the command as I was getting errors because it was splitting the command when reaching an & but I am still getting an error saying the directory is not found. Any help would be great. Thank you in advance.
