How to promote your Google packaged app?

Question

Google Workspace

Hello.
I have my app in Google Web Store - cMusic Player . I would like to tell users of Google Chrome about it. The application is not commercial, so I would not want to spend money on advertising. Does anyone know where I can post a review or something like that?
The only thing I found was the site my-chrome.ru, my review was published there and the reviews seem to be quite good, but still the popularity of the application is relatively small, as is the number of users.
