Subject: [PATCH 1/2] Fix (Saving Images): Fixed a window proxy issue when
 saving images in the micro-frontend framework.

Added the `pickEventView` function to handle the window proxy issue in the micro-frontend framework, ensuring that the save image event is triggered correctly in different environments.
