Custom "details" link in the github pr checks

I saw that Chromatic action is able to change the "details" link in PR check and post an additional comment. Can someone help me to set it up in my own workflow? check the image for example

Seems the GitHub Actions: checks-action is a good fix to solve your problem:

jobs:
  test_something:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - uses: actions/create-outputs@v0.0.0-fake
      id: test
    - uses: LouisBrunner/checks-action@v1.1.1
      if: always()
      with:
        token: ${{ secrets.GITHUB_TOKEN }}
        name: Test XYZ
        conclusion: ${{ job.status }}
        output: |
          {"summary":${{ steps.test.outputs.summary }}}

The output field could help:

output:
Supports the following properties:

summary: Required, summary of your check
text_description: Optional, a text description of your annotation (if any)
