According to our application, if an user has installed our bot in the MS Teams, the userdetails will be captured in the Azure table. The user details consists of Username, E-Mail address, tenant id,ServiceURL and so on.
I could see that there are users assigned with different ServiceURLs like "https://smba.trafficmanager.net/amer/", "https://smba.trafficmanager.net/in/", "https://smba.trafficmanager.net/emea/".
I would like to know how the regions(amer,in,emea) are appended automatically and, on what basis the regions are assigned to the user? Is it based on the machine location?
Also, if i get a requirement to send some adaptive card to only US users, will it work if i send it to only the users whose service URL is "https://smba.trafficmanager.net/amer/"?
