How to achieve a split-screen-like operation on iPad OS26?

Hello everyone,
To make the iPad more efficient, iPadOS has changed some of the operations we've been accustomed to for years. For example, the split-screen operation I frequently used has been removed. So, I'd like to know, how do we operate the new multitasking view if we use VoiceOver? In other words, how can I achieve a split-screen-like function using VoiceOver?
