Uninstall apps in android 11

[Edited cocktail]

Today i was watching apps launcher demo, all was good but uninstall button was not working, i scan the code and realize that only telegram could be uninstalled with this method: 

        var action = "android.intent.action.DELETE";

        var uri = "package:" + curIcon.packageName;

        var cb = OnResult;

        app.SendIntent( null, null, action, null, uri, null, null, "result", cb )
