Custom app iframe limitation

'https://[URL].fibery.io/Asset_Management/Asset-Assignment' from frame with URL 'https://[URL].fibery.io/apps/new-app/'. The frame attempting navigation of the top-level window is sandboxed, but the flag of 'allow-top-navigation' or 'allow-top-navigation-by-user-activation' is not set."

I noticed this error when I tried to get the app to navigate using # to reference an entity (for a side panel to open). I don’t know if this is intended for security.

Having to open in a new tab (target=“_blank”) breaks the flow for users—they’d sooner the two-panel view. Is there a workaround?

So far custom-app cannot open Fibery Entity in a panel.
We are working on this and soon will enable this functionality, we know it’s a basic one.
