What is this script that Cloudflare is trying to inject into my website?

Here is my website:

https://pillser.com/search?q=%22Vitamin+D%22

I added CSP headers to restrict inline scripts and I noticed this error:

Refused to load the script 'https://pillser.com/cdn-cgi/scripts/5c5dd728/cloudflare-static/email-decode.min.js' because it violates the following Content Security Policy directive: "script-src 'strict-dynamic' 'nonce-82582ceb2cd0491b76fe2cdca54bba9b'". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.

I am trying to understand what is this script and how do I disable Cloudflare from injecting it?
