How to programatically Trigger DynamicDialog's animation

[tiho]

When DynamicDialog is closed via "X" button an animation is applied.

But I need to have close button in DynamicDialog instance and when the dialog is closed via activeModal:DynamicDialogRef.close() function, there is no animation.
How to trigger it' Is it possible to have an animation in this case?

In official documentation's sample there is no animation when a Chose Car DynamicDialog is closed after a car is choosen. (Find button)
PrimeNg V7 is used.
