I’ve found a way to solve my problem and add desktop shortcut instead of “installing” PWA:
- add an explicit PWA manifest to the wiki, e.g. as shown here or using my plugin based on this same solution
- this first step will not change anything, Chrome/Android will still only allow to “install” the wiki
- modify the manifest.json and change
"display": "standalone"to"display": "browser", save and reload wiki - now when making a shortcut, the browser is instructed to display the “app” in a normal browser UI, and so a normal desktop shortcut can be created
