How to publish an artifact?

[iMonZ]

Hey,

I have this workflow:

- name: Snapcraft build
      if: matrix.platform == 'ubuntu-latest'
      uses: snapcore/action-build@v1
      id: snapcraft
    - name: Snapcraft artifact upload
      if: matrix.platform == 'ubuntu-latest'
      uses: actions/upload-artifact@v2
      with:
        name: Linux Snapcraft
        path: ${{ steps.snapcraft.outputs.snap }}

How can I convert this workflow into samuelmeuli?
I mean how can I upload an artifact with this fork?
