Android：如何为Google Play控制台提供测试版的国家 - WISE更新？ [关闭] -- applications 领域 和 google-play-store 领域 android 相关 的问题

I have gone through some links for help, where I found that this is possible in the google play console.

We have one app in the play store since last 5 years and uploaded more than 200 updates. Know we need to set up a country-wise rollout. like if I upload app in the beta(open testing) and after testing, i want to roll out for 2 countries like UAE and Saudi Arabia. and after that, I want to roll out for other regions.

If yes, Is there need to create a separate app for all the regions? or we can just roll out the same app to the other regions from the beta?

Thanks in advance.
