How to set multiregional subdirectories in angular 8 + expressjs

We struggle to understand how to set in angular8 a multiregional subdirectory. We cannot find a specific example to follow, basically, we targeting as a subfolder, GB, US, CA, AU, NZ, IE. Is the same site for all and only English. Means will be the same route and content for all those subdirectories.

mysite.com/country/page-1

On which area we should set the country and subdirectory and also the big thing how this will work with express and angular Universal as SSR.

Our site is hosted on Azure + IIS

I'll appreciate all your help. Thx
