Webex Adaptive Cards - clear input content after submit

[dupontb]

Hello,

I'd like the content of the Adaptive Card to be cleared once the user click submit (like Microsoft Teams does).

I found someone having the opposite behavior where he wants the content to be kept (https://community.cisco.com/t5/webex-for-developers/webex-adaptive-cards-keep-the-content-of-the-card/td-p/4612192)

The behaviors are total opposite. So what's the right behavior using the Webex app and how can I clear the form once it's submitted? 

Thanks
