Godot 4.4.1 Game Engine while playing the project the window size is too large to fit the screen, as i am developing the game for mobile in portrait

Hi I am very new to Godot Game Engine, I am trying to make a game for mobile phone in portrait mode, the display window size I set is 1080 by 1920, now I try to run the project in my computer only half of the window shows how can I fix this, I want the whole window to show so that I can look at my project with out transferring the project to my phone.

The output I see when I run project is :

You can simply override the window size from the Project Settings > Windows > Size Override when running the game from the editor. You can also use this setting to test multiple aspect ratios.
