Is there a way to publish snap for multi-archs at once?

[twang2218]

I'm trying to create a snap build/publish for multiple architectures, e.g. amd64, ia32 and arm64, I didn't find a way to publish the snaps of multiple archs to the snap store at once. I have to call this action multiple times for now. Is there anything I'm missing?

Same here. Do we really have to have two separate blocks of YAML to do multiarch support in the Store?

It can be configured to build and publish using a github matrix:

jobs:
  snapcraft:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        arch: [amd64, arm64, armhf]
    steps:
      - uses: actions/checkout@v3

      - uses: snapcore/action-build@v1
        id: build
        with:
          snapcraft-args: --build-for=${{ matrix.arch }}
  
      - uses: snapcore/action-publish@v1
        env:
          SNAPCRAFT_STORE_CREDENTIALS: ${{ secrets.STORE_LOGIN }}
        with:
          snap: ${{ steps.build.outputs.snap }}
          release: edge

May be a similar example can be added in either this action or the build one.
