WP-Toolkit and cache clearing from wordpress

Plesk version and microupdate number

18.0.56 Update #4

We use WP-Rocket with our Plesk server. We are looking to enable NGINX caching and serve all content via NGINX.

WP-Rocket have suggested that the NGINX-Helper plugin has automatic compatibility with WP-Rocket however - They suggest that you have to add additional NGINX settings to allow the plugin to purge the NGINX cache.

Nginx Helper

Cleans nginx's fastcgi/proxy cache or redis-cache whenever a post is edited/published. Also does a few more things.

Because the NGINX function is heavily interface driven from WP-Toolkit I dont understand what needs to be changed to allow the NGINX helper plugin to purge the NGINX cache.

Should this just work out of the box or do I need to add more settings?

The setup link for the plugin just gives me this: Which is Easy Engine which we dont use.

Nginx + WordPress + fastcgi_cache with conditional purging

Using Nginx's fastcgi_cache for wordpress full-page caching is generally faster and with fascgi_cache_purge module and nginx helper plugin you can keep cache updated

Can you help me (and probably other users) understand what needs to be changed here? Or does the plugin just work without the additional setup.
