Step 3: Run the Package and Grant Permissions
- Open your device's Downloads folder or tap the completed download notification in your notification tray.

Step-by-Step Apple iOS Configuration (iPhone & iPad)
Apple iOS users can configure an optimized progressive web application that operates like a native app without requiring external enterprise profiles:
- Open Safari on your iPhone or iPad and navigate to the official J77 platform.
- Tap the Share button located on the center of the bottom Safari navigation bar (the square icon featuring an upward arrow).
- Scroll down the menu list and tap "Add to Home Screen."
- Confirm the app label as "J77" and tap "Add" in the top-right corner.
