A customer is embedding the Document360 widget inside Microsoft Teams using a SharePoint Framework (SPFx) webpart. Due to Microsoft Teams and SharePoint CSP restrictions, they host the widget on their own domain and embed it via an iframe, resulting in multiple nested iframes (Teams → SPFx Webpart → Customer iframe → Widget iframe). In this setup, the help button appears, but the KB panel does not load because the widget’s load handler relies on parent.window._widgetBody.preRender(), which does not work when it is nested. The customer has requested to provide built-in, stable support for the widget to correctly detect and handle deeply nested iframe scenarios, ensuring the KB panel loads as expected without implementing workarounds.
