Put github-script output on new line

H there,
I have a github actions pipeline that uses github-script to publish comments on my prs e.g

jobs:
  my-job:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/github-script@v6
        with:
          script: |
         const output = `line one n line two'
            github.rest.issues.createComment({
              issue_number: context.issue.number,
              owner: context.repo.owner,
              repo: context.repo.repo,
              body: output
            })

I want the output to be published on two separate lines but nothing works. Thanks for any suggestions
