@neomatrix369 after seeing changes here, it poluted too much the PR. Do you think is better to make smaller adds into new cleaner branch instead of using this spike branch to merge?

I've recreated new projects for quarkus and helidon chatbots to get the correct versions to work with websockets. Since I know them now, I could simply update the current projects...

If you can add a screen-shot or two of a working version of this PR that would be great, no worries if its not there 100%

This is the right time to now pluck the smallest change to make one bot work with websocket and the rest on REST API - then we can close this PR without merging and review and work on the other one. And slowly we can take parts of this PR and make new ones till we have merged them all - just like we discussed the last time.
