Stop desktop app from appearing in the macOS dock

[mrinalwadhwa]

Current

We're building a Desktop System Tray app for Ockam using Tauri, see #5228

When we start the app in macOS it shows up in the macOS menu on he top right, this is expected:

But is also shows up in the macOS dock, this is not desired.

Desired

Should only show up in the menu.

Steps to reproduce

You can run the app as follows:

cd implementations/typescript
pnpm install
pnpm build

cd ../../implementations/rust/ockam/ockam_app
cargo tauri dev

Source Code

The code for this is here:

• https://github.com/build-trust/ockam/blob/develop/implementations/typescript/ockam/ockam_app

This is likely the fix:

#[cfg(target_os = "macos")]
app.set_activation_policy(tauri::ActivationPolicy::Accessory);

We likely have to add to it to app setup here:
