Modal unsaved changes shake footer actions

[jaymitBeladiya]

Hi,

I have an app and want to implement a modal form in my app. If there are unsaved changes, the footer action should shake, and a message indicating "Unsaved Changes" should appear. Does anyone have an idea on how to implement this?
Currently, Shopify has implemented this feature in the 'Customer Contact Info Update' modal. For more details, please refer to the following video.

Their review team responded that the current version of app bridge does not allow developers to use that feature. Therefore, you can ignore this when Building-for-Shopify
