Currenty we are using Qlik Sense with some custom security rules for admins and stream admins and this works fine. We would like to enable a larger group of 'power users' to duplicate stream apps and make updates, but we foresee some challenges for this workflow. Currently app duplication can only be done via the Hub if you are the app owner. Also updating the app in a stream is only possible via the QMC.
What is your best practice for enabling users without providing too much QMC access? Do you have a set of security rules for this or maybe there is a good mashup extension for this?
