Critical: Cannot customize iOS permission purpose strings (blocking App Store submission)

My app is being rejected by Apple under Guideline 5.1.1 because the permission purpose strings in Info.plist are not sufficiently descriptive. Currently, Base44 generates these strings automatically and does not allow customization. This is blocking App Store approval, as Apple requires explicit and descriptive purpose strings for location, camera, and photo library usage. This needs to be configurable before IPA generation.
