Chrome lately added Chrome App Launcher to the dock, in order to lunch installed chrome apps.
Can I create Alfred workflow in order to run them through Alfred?
Yes, you can.
They are stored in ~/Applications/Chrome Apps
(where ~
is your user's home folder), so you can add them to a workflow action like 'Launch Apps/Files'.
The easiest way though to add an app to the 'Launch Apps/Files' is to search for it in Alfred and drag the Alfred result into the 'Launch Apps/Files' list.
If the Chrome App doesn't show in Alfred results at all, add ~/Applications/Chrome Apps
to the 'Search Scope' in Preferences > Features > Default Results.
