My Cloudflare apps are not showing

Hi! I’m building a social-networking platform and my website for it uses Cloudflare. I found the apps to be an easy way to modify and enhance the experience on my website. However, it does not seem to work on my, and other people’s browsers. I have installed PACE, Smarttarget exit popup, Flashcard, and Cookie Consent, however, none of those apps are even appearing. What am I doing wrong, and how can I resolve this?
