How to download from my Region?

Hi all,
I installed Jitsi on my server and it works great. I am located in Shenzhen China. 100% of my clients uses Ipad and Iphone, unfortunately, Jitsi isn’t in the app store in my location. Rather, than having my clients open a new apple account in area where the app is - which is very complex in China. Can you direct me to where I can download the app ,other than apple store. Or allow me the put the app on my server. Or open the app in the Apple store in China. How to solve this challenge?
