          # Posts a comment to the PR using the 'update' behavior.
          # This creates a single comment and updates it. The "quietest" option.
          # The other valid behaviors are:
          #   delete-and-new - Delete previous comments and create a new one.
          #   hide-and-new - Minimize previous comments and create a new one.
          #   new - Create a new cost estimate comment on every push.
          # See https://www.infracost.io/docs/features/cli_commands/#comment-on-pull-requests for other options.
