GIST_TOKEN

[AlexHedley]

Is GIST_TOKEN an existing one like GITHUB_TOKEN or do you have to create it?

action.yml

  gist_token:
    description: |
      GitHub OAuth/PAT token to be used for accessing Gist to store
      test results report. The integrated GITHUB_TOKEN that is normally
      accessible during a Workflow does not include read/write permissions
      to associated Gists, therefore a separate token is needed.
      You can control which account is used to actually store the state by
      generating a token associated with the target account.
