FaceTime in Pakistan.

Hello,

As in ios 12.4 update apple officially activated FaceTime in Pakistan. My question is that i bought my phone from Dubai . In which FaceTime is blocked but i am using my phone in Pakistan as the launch FaceTime in Pakistan so how can i use it? Or download it? I can’t find it in settings and even in search bars. I shared a screenshot from a Pakistani mobile site. My device is iPhone XS Max.
