navigator.getInstalledRelatedApps() is empty on Chrome in Windows 11

Something must be missing, but I just don't know what. Because the installed web app should be listed in the array when calling navigator.getInstalledRelatedApps() but the array is just empty.

Chrome (146.0.7680.178) Windows 11 Console Output

On https://www.swisswebcams.ch/ (with installed web app)

Call in Web App

if('getInstalledRelatedApps' in navigator) navigator.getInstalledRelatedApps().then(apps => console.warn(apps));

Assetlink

[ { "relation": ["delegate_permission/common.handle_all_urls"], "target": { "namespace": "web", "site": "https://www.swisswebcams.ch" } } ]

Is this even needed for navigator.getInstalledRelatedApps() to work?
