Page duration & Next / Previous buttons

Hello all,

I am creating a presentation and I would like to have the users stay on a page for a pre-determined amount of time.

Once this time goes by, I want the next arrow to appear.

However I would like that if they have waited the amount of time, and click the previous button, to have the next arrow be present right away.

I am not sure if this is possible and if anyone has done anything similar I would love to hear it.

Thanks in advance,

OTR-
