Migration of Visual Builder application as App extension in VB Studio

Summary:

Migration of Visual Builder application as extension

Content (required):

We have developed an application in visual builder initially which is using Fusion objects and is embedded in Fusion application.

Now considering the advantages of App extensions and to avoid x-frame issues, we want to convert the developed visual application as app extension. We tried importing but we couldnt import as app extension as it is a visual application.

Is there any way to achieve this?
