restyling controls on WinUI3

I'm developing on WinUI3, and trying to restyling button control.

Document says

For WinUI 2 controls (Microsoft.UI.Xaml.Controls namespace), the default style is defined in the metadata, so omit BasedOn.

Currently using Button control is in namespace
Microsoft.UI.Xaml.Controls.Button is UinUI 2 controls, right?
and button appearance is different between write BasedOn or omit.

BasedOn ... button corner is rounded.

omit ... button corner is not rounded.

what is the better way to restyling controls?
or is there document for WinUI3?
