How to validate EnvoyFilter has been applied successfully in the production

Newbie here. Sorry if this is a simple question.
We added HTTP2 workflow control in our clusters according to the following article. Is there any way to validate this setting has been applied successfully in the production? Can we see this setting via config_dump or some kubectl commands?
