Safari extension distributed in a notarized app with Developer ID wont open unless "Allow unsigned extensions" is selected

Safari extension distributed in a notarized app with Developer ID wont open unless the Safari option "Allow unsigned extensions" is selected.

We're building a Safari web extension and experiencing an issue to see it among extensions in Safari after installing the container app to /Applications and launching it.

The app and extension is notarized and signed with Developer ID

We seemed to have all checks good, the extension can be installed only if Safari is allowed to run unsigned extensions.

Could anyone assist to debug/resolve this issue?

Thanks


This is expected behavior.

Only Safari Web Extensions distributed through the App Store can be loaded without allowing unsigned extensions.
