How to restrict 'web panel' to a confluence 'general page'?


I am trying to restrict a web panel to appear only on pages for which I can use the following condition in the atlassian-connect.json file -

    "condition": "has_page"

But there doesn’t seem to be any condition that restricts the panel to appear on General Pages defined in the atlassian-connect.json file.

Is there any way to achieve this?
