How to reset App Store's window size to default on MacBook?

Hi all,

I've accidentally dragged App Store window on my MacBook, and now its size is a bit weird. I'd like to reset its window size to default so it would look like how it looks when you open the App Store for the first time. Is this possible in any way?

I've tried to delete the 'com.apple.appstore.plist' file, but it didn't help.

Thanks in advance!
