[Closed] SDK Create Temporary Viewport

Hi, I am trying to create a temporary viewport. Where it will create a viewport using the info of the active viewport, and then be destoryed after I’m done using it. I am looking for some like the Create Preview where it creates a viewport and then destorys itself once its done. I have had a look through the sdk doc’s and can’t find anything about how to create a viewport. Any ideas on how I would go about this ? Thanks
