This new IPresentationSession interface enables an application to do a multi-document presentation, something which isn't possible with the existing API. As a practical example of this consider presenting both your Mobile Driving License and your Vaccination Certificate in a single transaction. Bug: 197965513 Test: New CTS tests and new screen in CtsVerifier Change-Id: I11712dca35df7f1224debf454731bc17ea9bfb37
