decompress cache to subfolder

[jlg4]

Hi

I have a config:

   - uses: bahmutov/npm-install@v1
      if: needs.check.outputs.build_web_clients == 'true'
      with:
          working-directory: src/SoMeSociety.Brandarmies/Client.Shared

but it seems the cache is decompressed to a different folder and thus not speeding up my build. what am I missing?

Thanks!
