getInstalledRelatedApps is empty

I am trying to get getInstalledRelatedApps documents but it always return empty as [].

Code

$(function () {
    window.addEventListener('load', () => {
        if ("getInstalledRelatedApps" in navigator) {
            navigator.getInstalledRelatedApps().then((relatedApps) => {
                relatedApps.forEach((app) => {
                    console.log('platform:', app.platform);
                    console.log('url:', app.url);
                    console.log('id:', app.id);
                    // This field is provided by the UA.
                    console.log('version:', app.version);
                });
            });
        }
    });
});
