Summary

Issue #49 mentions building an ESM module. I noticed ESM is only built on our core library and not our kits. When we get to refining our CI/CD more, we should restructure and have this be more automated so not every kit needs to be updated, but for now I am adding this to quickly get it to market.

Testing Plan

• Was this tested locally? If not, explain why.
  Builds esm file locally
