The new `window.setMainMenu(menu)` function allows developers to create a native window menu for GNU/Linux and Windows, and an application menu for macOS. Developers can call this function multiple times to dynamically update menu items. When a user clicks a menu item, the framework triggers a `mainMenuItemClicked` event with the relevant data. On macOS, key accelerators and pre-defined actions can be registered, but currently, GNU/Linux and Windows only display keyboard shortcuts within menu items without registering

A Dead Letter Queue (DLQ) is a secondary queue used to store messages that fail processing in the main consumer queue, helping to preserve data integrity in distributed systems. DLQs enable the troubleshooting and recovery of failed messages without disrupting the main workflow. They employ a redrive policy to determine how many retries a message will receive before being directed to the DLQ. It's important to note that using DLQs can interfere with message ordering in FIFO systems. Different messaging systems have specific implementations for DLQs:
