I have created a Main MegaMenu with 3 levels. I know the menu entity id for the menu item. Now I wanted to alter (push specific content to the specific menu item). I know the entity id (menu id) for those menu items. I want to do that programmatically and not by adding block content and assigning that blocks to those specific menu items
Provide a hook name in which there should be a way to match the menu entity id to push custom content
