Is it possible to change the fixed aspect ratio of the screen for iPhone-only app running in M1 Mac?

Hello, I am trying to run an iPhone-only swiftUI app that I have made on the M1 Mac to test how it would look. However, I have noticed that the window aspect ratio is fixed to a screen size similar to the iPhone SE line.

Is it possible to change the fixed window size? For example, I would like to change the current window's aspect ratio to iPhone 15's aspect ratio which is 19.5:9 and fix it there instead of the current aspect ratio in the picture.

The picture is the current aspect ratio which I consider the height of the current window to be a bit low in the mac and wouldn't mind the app to take up a bit more space. Thank you.

iPad apps even if you change the size of the Window are just rescaling to the window (still full res). Have to require iOS 13, and jump through some hoops to allow resizing the application window (and not always be full res). But that's iPadOS on macOS, and not iPhone.

Is it possible to change the fixed aspect ratio of the screen for iPhone-only app running in M1 Mac?
