How to create new window with svelte

[heavy swallow]

tauri v2.0 with svelte

Trying to create new window that connected to svelte file like the main window does with +page.svelte.

I found how to create new window here, but there are no info how to connect it to file (like .html or in my case .svelte) https://v2.tauri.app/reference/javascript/api/namespacewindow/#window

While trying using code from there - I have errors (second screenshot)

Generally I want new window be like child window to main, so when I close the main for example - new window (child) closes too. But that's in future, just to describe what I need from beginning

you'll want to use new WebviewWindow() and provide it a url like /newWindow

Am I need to allow creating new window somewhere? I tried all possible url, but it keep giving 404

Don't add .html, sveltekit doesn't need it

still the same

you have a routes/newWindow/+page.svelte file yeah?
