No interface object in widget_conversation_card

Hey Community,

I have an issue with showing a notification from a Freshcaller app placed in both, the caller’s conversation_card and the widget’s widget_conversation_card.

What I try to achieve is to show a notification if the contact has specific properties (contact fields) set.
This works perfectly fine in the product itself, but when loading the app in the widget, the interface object is missing in the client, leading to the following error:

Here’s my client object:

According to docs, showNotify can be used irrespective of the placeholder. See here.

Am I doing something wrong? How can I show notifications in the widget?

Best
Tom
