If I get it right, you want the animation to stop for a second so the viewers will be able to see all the details.
Then you need to change the final keyframe position in the Animation tab for this slide (double-click the slide, pick the layer, then go to Animation).
If you need a bit more help with that, for example, a step-by-step guide, contact our Support team here: https://smartshow-software.com/support.php
