How to switch editor tabs with Python?

I can open asset in new tab with

 assets= [unreal.load_asset('/Game/myasset')]

 aes = unreal.get_editor_subsystem(unreal.AssetEditorSubsystem)
 aes.open_editor_for_assets(assets)

Asset opens in editor. Editor SWITCHES to this asset.

But how to switch back to main level asset?
