window.webContents.on("before-input-event", (event, input) => {
  if (
    (input.control || input.meta) && // Control for Windows/Linux, Command (meta) for macOS
    (input.key === "+" || input.key === "-" || input.key === "0")
  ) {
    event.preventDefault();
    console.log(`Blocked zoom action: ${input.key}`);
  }
});
