Question Apache module proxy_html missing?

[Azurel]

Apache in plesk have so many installed proxy-modules

proxy
proxy_ajp
proxy_balancer
proxy_connect
proxy_express
proxy_fcgi
proxy_fdpass
proxy_ftp
proxy_http
proxy_scgi
proxy_wstunnel

Does it have a specific reason that module "proxy_html" is missing here?
mod_proxy_html - Apache HTTP Server Version 2.4

Might you share your OS & Plesk version.

For example under Ubuntu & Plesk 17.8 mod_proxy_html exists

Sorry, I've forgotten

Plesk Onyx Version 17.8.11 Update #58
CentOS Linux 7.6.1810 (Core)‬

I assume you have to install it like #yum install mod_proxy_html and afterwards it should be visible in the plesk panel > tools & settings > apache settings

Yes, but I wonder why all other proxy-modules are available as default, but this one not.
