Egypt is not listed in the region settings how it can be added?

Usually that means that Microsoft does not have a license from the government to operate there with the service in question.

Assuming that you're trying to use an Xbox console, it's because Egypt is not a supported region for any Xbox hardware or services aside from PC game pass

This is the list of gamepass supported regions. If you notice, Egypt is not listed. While it is on a list to be added, it’s not live, and currently unsupported outside of testing.

Egypt is not a supported region for GamePass Xbox consoles or other services, you cannot access Xbox online services, and Microsoft has no legal right to provide them to you.

Ther is no information. on when Egypt might be added, any a. announcements will be via Xbox news and social media sites.
