How to activate QA PREFERENCES (settings, dev options, QA Preferences) then asks for my QA Code?

How do I get my QA code so I can use the brave VPN and the other developer options that I cannot use unless I enter AQA code. Can brave give me AQA code so I can use all of the features in the developer options? I have a Samsung Galaxy phone I use desktop mode in the brave app. That is my system set up so what do I need to do to use the rest of brave features? Thank you for your time in reading this and all of your replies if any.

Hi. Where are you seeing this QA code prompt? As far as I know, vpn + firewall is not available for android devices, only iOS. Can you provide more details?
