How to Simulate for iPad Air 2?

I'm learning to develop iOS apps.
And I'd like to test it on my iPad Air 2.

My Xcode is set up as follows:
iOS 13.0
Xcode 12.3
Swift 5.3

My iPad is on iOS Version 14.3.

I had my iPad Air 2 set up before, but its simulator disappeared when I upgraded the Xcode version.

How do I set up Xcode so I can simulate/run apps on an iPad Air 2?

Thank you very much in advance.
