Submodule initialization with private sumodule fails

Hi, I am testing v2. My goal is to initialize submodules behind a private repo with the whole history.

I am not sure if I am doing this right, but I am doing this.

    - uses: actions/checkout@v2
      with:
        token: ${{ secrets.CI_PAT }}
        submodules: 'true'
        fetch-depth: 0

And receiving this output.

Run actions/checkout@v2
/usr/bin/docker exec  cf6073467e49ed136c89b40c65140167d4da6b133a966b11d7b7277f30c084cb sh -c "cat /etc/*release | grep ^ID"

The repo and the company name was renamed here, but they are good The browser opens the (right) URL.

Yeap, I tested this yesterday as well and it is working now. My issue is that my submodule is private.

But this is working as well now.

    - name: Checkout with submodules
      uses: actions/checkout@v2
      with:
        submodules: 'true'
        token: ${{secrets.CI_PAT}}

Someone told that V2 does not implement submodule but this info is not on README. So it will be nice to put it there if it is right.
