Optimizing PageSpeed ​​Insights, how to increase caching time for images and documents in .htaccess file?

Question

htaccess

PageSpeed ​​Insights recommends increasing the caching time for images and files from 60 minutes to a higher value. I added the corresponding detectives to the HTACCESS file in the root folder of the site, but there is no result, why does the caching time not increase if all commands are registered?
.HTACCESS File Code
Header append Cache-Control "public, no-transform"
Header set Cache-Control "max-age=2592000, public"
Header set Cache-Control "max-age=2592000, public"
Header set Cache-Control " max-age=172800, public, must-revalidate"
Header set Cache-Control "max-age=172800, private, must-revalidate"

I noticed a dependency that files that contain the @ symbol in the name are not cached, example "[email protected]"
