When the timeline ends, nothing happens. All the objects remain on the screen, and all interactions continue to function.

So actually, once the timeline reaches the end, it no longer moves. It will sit without taking any action for infinity. The only exceptions to that are if you set a trigger to change that behavior, for example: object ends or disappears before timeline ends, slide advances when timeline ends, or some trigger initiates when timeline ends. Given your question,  you probably don't want to do any of those things

There is not really any other infinite setting.
