New redmi note 13 split screen wont work

[kaygusuz abdal]

I recently bought a new Redmi 13 and started using it, but I noticed that I could not use the features of splitting the screen in two or opening incoming notifications as tabs that I had on my previous phones. When I enter the open applications tab and hold it down, no option appears. My version is 1.0.6, the latest version, neither to lock nor to split
