commit 9b2af883522284efe4bffe4ca05d1cadb95f11f9

    webapps: Search for apps by app id
    
    The `keywords` list is used to search for an (installed) app, to show
    its details, like from the Activities and the app context menu in the Shell.
    No other plugin knows about installed web apps, thus search for them by
    the app id.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1927
