Hello, our app currently runs on version 18.0.2 on production mode. I noticed Token Exchange can only run on dev mode. Is there any version that allows the Token Exchange feature to run production mode?
Where is mentioned that Token Exchange only runs on dev mode?
It‘s a „preview feature“, you can enable preview features also when running in prod mode. There‘s nothing against it.
Okay thank you, also really enjoy your videos online 
Additionally, if I am running version 18.0.2, can I enable Token Exchange feature through my Dockerfile. I am currently doing this in my Dockerfile:
ENV KC_FEATURES=token-exchange
Lastlly, what is a way to verify you have installed Token Exchange successfully?
It‘s all mentioned here what you have to enable and how it currently works. If you use env vars, cli args or conf file, it‘s up to you how you want to configure your environment.
Hopefully you know that you use a more than outdated version of Keycloak (approx. 2,5 - 3 years). It‘s insecure and receives no updates… Upgrade to the most recent version.
