@eddy-ccc Is the github secret token needed here? Our other YAMLs don't have it. Not sure if this is just an additional precautionary step or necessary for the force check before merging to main

@KELSEYDOWLING7 Great question! This is unique to GitHub... secrets is an object provided to us by GitHub Actions itself that we can reference within the yaml. The GITHUB_TOKEN is an attribute of that object, which is created for us by GitHub, and allows the repo to authenticate with the GitHub API during the testing workflow, without us having to create or manage a personal access token. GitHub automatically mints it at the start of the run and revokes it when the job ends.

@eddy-ccc Ah! Ok perfect. That was moreso my question, whether we'd have to create and maintain the token. Thanks!
