What px should be used for iPhone 13pro

When I export a game to gd.games and then use the link to open it on an iPhone 13 Pro, a black line appears on both sides. The game properties are defined as below:

  • Picture size: I tried 1170x2532, 390x844, 693x1500 px pictures.

In Game Properties:

  • Defined the same in the Resolution and Rendering,
  • Set “No changes to game size” in Game resolution resize mode,
  • Set “Portrait” in Device orientation (for mobile)

Anyone can help?
