How to access files stored in /github/workspace?

Question

I am trying to create a workflow for my repo using an action which auto generates a changelog. Ideally the generated changelog should be present in the root of the master branch. But the build log of the workflow states that the CHANGELOG.md file has been stored in /github/workspace. How to solve this problem or how to access the CHANGELOG.md file?

name: Generate Changelog
on: 
  push:
    branches:
      - master

jobs:
  build:
    name: Update Changelog
    runs-on: ubuntu-latest
    steps:
      - name: Checkout master
        uses: actions/checkout@v2

      - name: Set up changelog
        uses: heinrichreimer/github-changelog-generator-action@v2.1.1
        with:
          token: ${{ secrets.GITHUB_TOKEN }}

It outputs the file to your current working directory on your runner. It creates a link between the docker dir the github-changelog-generator-action is running on.

E.g. /usr/bin/docker run <... omitted> -v "/home/runner/work/TestGithubActions/TestGithubActions":"/github/workspace" when the repository name containing the workflow is TestGithubActions.

Adding ls to your workflow

name: Generate Changelog
on: 
  push:
    branches:
      - master

jobs:
  build:
    name: Update Changelog
    runs-on: ubuntu-latest
    steps:
      - name: Checkout master
        uses: actions/checkout@v2

      - name: Set up changelog
        uses: heinrichreimer/github-changelog-generator-action@v2.1.1
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
      - run: |
          ls

outputs this:

Run ls
CHANGELOG.md
