How to verify if apq is enabled ?

Hi, I want to use this module to enable apq caching for our drupal graphql but am not too sure how to use this.

I have this module installed and enabled in our environment, but does that mean apq is running? If so how do I verify? Or do I need to create an apollo server separately in order to use this module?

To add to this I am using the drupal grapql module to do our queries.

Thanks!
