[feat] Shift click on taskbar icon to create new window

[abose]

Describe the problem

In Windows, shift-clicking on a taskbar icon will launch another instance of the app. Is there a way to do that in a Tauri window? I couldn't find it in the docs/search.

Attached screen recording below:

steps:

1. Open a Tauri demo app in windows.
2. Press Shift key and click on the taskbar icon.
3. Observer that nothing happens

Expected behavior:

Another window/app instance should be opened (Or an API to control this behavior).

Describe the solution you'd like

Shift click your app icon in the taskbar is the same as opening your app second time. If you want to change the behavior to spawn a new window, then use a single-instance plugin like tauri-plugin-single-instance or tauri-plugin-highlander.

@amrbashir the problem is that shift click or middle mouse click has no effect in tauri apps. It does not spawn a new instance, which is the wanted behavior here.

p.s. i tested this locally when we talked about it on discord, both tauri dev and tauri build, the latter before and after installing the msi

@FabianLars Can you please try again, I just tried it, and it just works and There is no special handling for this as far as I researched.
Here is what I tested using examples/api:

1. Running the app from target/release -> Doesn't work
2. Create a shortcut for the target/release app and run the shortcut -> Works
3. Install the app and run the exe directly from the installation directory -> Works
4. Install the app and run the shortcut in the start menu -> Works

@amrbashir you're right, it works sorry. I think i only tested debug builds (tauri build --debug) which don't work. (probably because of some identifier mismatch because of the terminal wrapper?)
