How do I force window to start game at larger size?

I'm working with a really tiny game size (320x180). When the project / game launches in the popup, it's set to that small of a size. But what I'm looking for is to launch the game at a bigger window size, like 1280x720.

I've tried setting the canvas size at layout start, and setting the layout scale to 4.0 but the window for some reason still launches at the original small size.

You can edit the size of your Layout by click on the specific layout

Or edit the viewing window by clicking on the Project name

I don’t think the layout size changes the physical window size. And changing the viewport does work but then the “layout square” where the dotted line is becomes a lot larger, so I have to scale up my pixel art assets or zoom the layout or something?

I am just surprised there’s no “window size” option. Like some engines you can set the window size and also the resolution size.
