The "Polaris For VSCode" extension has a bug, so I created this working solution for now.

1. Download polaris-companion-0.0.1.vsix from the repo.
2. Open VSCode and go to Extensions.
3. Click the three-dot menu and select "Install from VSIX..."
4. Find and open the .vsix file to install.

It works same as "Polaris For VSCode." extension.
