Cloudflare Edge cache TTL

I've been testing Cloudflare, and I have Edge TTL set for 1 month for everything in the images folder. I'd like to see if this is set correctly, but in the Response Headers I don't see an EDGE TTL expiry. Is there any way for me to see when the cache will expire for an object in Cloudflare?

Here's the sample headers:

Because EDGE TTL expiry are not reflected in the response header. They use this for their internal parameter to store files. Visit this link for more detail https://support.cloudflare.com/hc/en-us/articles/200168376-What-does-edge-cache-expire-TTL-mean-
