To add to rayelkhoreply, this could be achieved with custom code. Since IAMs can handle HTML, CSS and JS which are the same languages most of the web runs on, if doing a swipe message is possible on a website, there is a very high chance you could do it in an IAM using CSS animations.
Some CSS example:
30+ CSS Reveal Animations
This could be either one of these 2:
- Custom IAM: https://www.braze.com/docs/user_guide/message_building_by_channel/in-app_messages/traditional/customize
- MultiPage IAM: https://www.braze.com/docs/user_guide/message_building_by_channel/in-app_messages/drag_and_drop/create/#multi-page
Without seeing the functionality, it would be hard to tell you how it can be done but I have worked on something similar and depending on how up to date your Braze SDK is, data and logic required, it is very possible with Braze's In App feature. I do not believe this is a content card function but it could be.
