2. Configure a local Temporal instance to enable archiving in gcloud storage
3. Start all dependencies locally and run the temporal server
4. Start a sample workflow multiple time
5. The workflows are correctly shown in the UI
6. Wait several minutes until all closed workflows have been archived in gcloud
7. Click on the link to show the archive
8. Each workflow will be listed twice
