I want the last slide to zoom text and at the end of the text to keep all the text on the screen.

Here is what I did.  I used insert Title to create this slide slide.  I then added text to it.  I then moved all of this to be my last slide. The zoom works great, BUT at the end of the zoom the screen goes blank.  How can I keep the text on the screen at the end.  I am showing a video I made and at the I want the last slide to show on the screen as I talk to the audience with the text showing.
