Ionic Ios app on TestFlight not able to test by Internal testers

Hi All
I uploaded ionic iOS build from Azure DevOps pipeline to TestFlight.
Build is successful its also showing testing but invitation to test build is not triggering to internal testers.
When I searched on web I found below link which says to edit info.plist.

Based on this my question is
1.Can we edit info.plist which is inside our platform folder and add related keys?

I am stuck for my app testing
someone please reply
