Grid layout Android Studio

[My project]

I am trying to learn about Android Studio Grid Layout with a simple example with four buttons. I have made three copies of a button to get four buttons but they stay on top of each other. I have set 2 rows and 2 columns. Shoulden't the buttons adapt to four separate buttons in a grid?

I have installed Android Studio Chipmunk and I use Windows 11.
