Thanks for your Feedback.
Nevertheless we are using babel-preset-env. This should take care about asnyc/await so far i know.

Currently without that I get an error about transform-runtime missing. If I missed something then great otherwise this seemed to fix it for me.

@OmgImAlexis I guess you are right. I am open for PRs 🙈
