[HELP] setting up custom protocol and apps for websites

:information_source: Info

Version: 3.16.4

:speech_balloon: Description

I am trying to set up a custom protocol and apps for websites. I want my custom protocol to be dakanji://, so I set protocol_activation: dakanji,http,https. Which works great. My problem now is that I cannot get apps for websites to work. I want the app also to open when opening https://dakanji.app/app/. Therefore I set app_uri_handler_hosts: dakanji.app

:scroll: Pubspec.yaml

 msix_config:
  display_name: DaKanji
  protocol_activation: dakanji,http,https
  app_uri_handler_hosts: dakanji.app
  publisher: CN=EC6A3F44-67FB-44EF-B45B-1DACD55293B9
  publisher_display_name: DaAppLab
  identity_name: 61015DaAppLab.DaKanji
  logo_path: ./assets/images/dakanji/icon.png
  capabilities: internetClient
  execution-alias: DaKanji
  languages: en-us, de-de, ru-ru, ja-jp, zh-cn, it-it, fr-fr, es-es, pl-pl

dev_dependencies:
  msix: 3.16.4

With this setup the msix builds however, it does not open my app when visiting the website

When setting app_uri_handler_hosts: dakanji.app/app/ the msix builder will crash.

Any ideas what could be the problem?
