Hide Specific Channel Groups from PaperUI Thing Creation

thank you for your reply. i only know the way to setup a proxy directly on the OH server path (as described in the tutorial here: https://docs.openhab.org/installation/security.html) … do you know a tutorial/help which shows a amateur in proxy server to setup a proxy for each ui or something like that? that would be very helpful. but maybe it is meaningful to describe my challange/problem directly in an own topic, please see here:
