I am trying to provide specific users access to the app on Qlik Sense server. As per my knowledge, Qlik Sense provides access at AD groups level from the custom properties of the app and not at a user level. I tried using Managing Security using Section Access to restrict access but even in that case, the user can at least view the app in the stream. Please let me know if there is anything that can be done to restrict access at user level such that the app is hidden as well from the unauthorized users who do have access to the stream in which the app is published
You may use Security Rules from Qliksense QMC to manage your user to view Stream in Qliksense Hub.
Here is a link from Youtube to guide how to use Security Rules.
