AppOptics - licensing if you own regular Solarwinds?

Greetings All.

Question: if I have a fully licensed version of Solarwinds do I also have AppOptics, or is there a separate license?

Details: my company owns and operates Solarwinds with NPM, SAM, NCM, etc. version 2022.4.x (i.e. up to date).  We have an emerging monitoring need for Prometheus that I believe will require AppOptics.

Do we need a separate license and installation for AppOptics, or does AO come with our current installation?
