PWA shortcut says “app not installed” when clicked

I found out about PWA shortcuts today and I tried setting it up but I can’t figure out how to make it work as I get an error “App Not installed” whenever I click the shortcut.

The website is https://specy.github.io/skyMusic/ my manifest shortcut contains this:

shortcuts": [
    {
      "name": "Open composer",
      "short_name": "Composer",
      "description": "Open the composer page",
      "url": "./#/Composer",
      "icons": [{ "src": "manifestData/composerIcon.png", "sizes": "192x192" }]
    }
  ]

I think The issue I’m having comes from the react hashrouter, the final link should be https://specy.github.io/skyMusic/#/Composer

I filed a bug report and it got the attention of an Android developer (although the bug ticket was never updated). It seems to have been fixed as of ~May 11th.
