Cannot run action on Act

I would like to use act: https://github.com/nektos/act to test my actions.

However, at the tailscale step I got :
failed to connect to local tailscaled; it doesn't appear to be running (sudo systemctl start tailscaled ?)

It should no matter but on the machine running act I also have tailscale configured and running.

Here is the github flow :

name: Pull request
on:
    pull_request:
      types: [opened, synchronize, reopened, ready_for_review]
      branches:
        - main

jobs:
  preview-deployment:
    if: github.event.pull_request.draft == false
    name: preview-deployment
    runs-on: ubuntu-latest
    steps:
    - name: Checkout 
      uses: actions/checkout@v4

    - name: Setup Node
      uses: actions/setup-node@v4
      with:
        node-version-file: package.json

    - name: Install Dependencies
      run: npm install

    - name: Tailscale
      uses: tailscale/github-action@main
      with:
        oauth-client-id: ${{ secrets.TS_OAUTH_CLIENT_ID }}
        oauth-secret: ${{ secrets.TS_OAUTH_SECRET }}
        tags: tag:MySuperTag

    - uses: pulumi/actions@v5
      with:
        command: preview
        stack-name: dev
      env:
        PULUMI_ACCESS_TOKEN: ${{ secrets.PULUMI_ACCESS_TOKEN }}

Thanks in advance ! :)
Have a great day

Start with the tailscale/github-action@main step in the supplied workflow and reproduce it with act, focusing on the reported failure to connect to local tailscaled. Compare this with running the same workflow on GitHub Actions; done means the incompatibility is fixed or the supported behavior and limitation are documented.
