Files downloaded notification - when thumbnail is displayed in Recommended files on dashboard and Talk Conversation

If we have shared any file via deck card or in talk, the icon of same is displayed in the recommended files app on the dashboard.

everytime a user logs on and the thumbnails are generated which is triggering the notification that the file was downloaded, whereas the user hasnt clicked on the file to download the same.

The notification should not get triggered if the icon is displayed in the app dashboard.

Another observation, if someone visits a chat in talk using browser, the notification for downloading of shared pic in chat is also given, this is happening every time the user visits the conversation

kindly change necessary code
