Brief Summary:

Using the below code snippet, the notification does not show up in Cinnamon Desktop Environment. However, the notification sound can be heard. I am using Cinnamon right now, and am testing other DE as well. Also, using notification on App instead of AppHandle does show the notification.

Code Snippet

use tauri_plugin_notification::NotificationExt;

// Learn more about Tauri commands at https://tauri.app/v1/guides/features/command
#[tauri::command]
fn greet(app_handle: tauri::AppHandle, name: &str) -> String {

    if let Err(e) = app_handle.notification().builder().body("body").title("title").show() {
        println!("failed to show notification: {:?}", e);
    }

    format!("Hello, {}! You've been greeted from Rust!", name)
}

#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
    let app = tauri::Builder::default()
        .plugin(tauri_plugin_notification::init())
        .plugin(tauri_plugin_shell::init())
        .invoke_handler(tauri::generate_handler![greet])
        .build(tauri::generate_context!())
        .expect("error while running tauri application");

    app.run(|_app_handle, _run_event| {});
}

Edit: There is no issue on Gnome Desktop Environment. So, we can safely assume that this bug is present only on Cinnamon Desktops.
