I am trying to come up with a way of having the touch bar on my mac display the network calls being made on the page I am navigating, I already have an extension that captures the exact network calls i need so If it is easier to just have an extension pass information to the mac touch bar then that would be even better.
I already tried using BetterTouchTool without luck.
No, the Chrome extension platform does not have TouchBar support. You may be able to accomplish your goal by creating a native app in Objective C or Swift and using the nativeMessaging API to share data between your extensions and application.
