How to enable app sandbox in iOS keyboard extention?

I am building a new iOS app - keyboard extention which include network connection. While testing in on simulator I was able to use network(POST request) but when trying to run it on my iPhone 13 I am getting this: error: A server with the specified hostname could not be found.: A server with the specified hostname could not be found.

it feels like the app might not have permission to access the network at all (when test run it on real iOS device)

I search online for a solution and I found out that I need to set Provisioning Profile with sandbox capabilities. And later add it to my target.

I do not find in developer.apple.com -> app ID any mention of App Sandbox so my current Provisioning Profile dont include it so I can't also add it on my target(Xcode).

I tried to add to my current Provisioning Profile (app id) app sandbox but did not find any mention of it.

I added app sandbox to the .entittlemnts file. I clean build folder and rebuild it and still app sandbox do not exists.

the solution to my issue was to allow full access in keyboard settings on my iPhone.
