In this update, we focused on enhancing the sharing features. Now it's possible to set the expiration date of shared and live links, as well as direct shares. On top of that, each link can be configured with parameters that modify the behavior of the presentation player.
To set the expiration date, open the presentation and navigate to the Share presentation view from the sidebar on the left, then click the Expiration date button to the right of the shared link. The date picker will open where you can choose a date.
To set the parameters of the shared link, click the Sharing options button to the right of the link. The dialog will open where you can modify the behavior of the presentation player and add UTM parameters.
