Excel Mac - UserForm

Question

I am so close to being able to fully use the UserForm on Mac Excel.

In the VB Editor I needed to go to Tools->References and Enable: Microsoft Visual Basic for Applications Extensibility 5.3

Now if I add the following code in a sub and run the sub:

set objForm = ThisWorkbook.VBProject.VBComponents.Add(vbext_ct_MSForm) 

It actually works! A form control gets added in the project browser, I see the form and have the toolbox available and all properties. But its one and done, I can't figure out how to go back and edit the form once I close that window. I can edit the code but never get the designer window to pop up again.

I feel like its a hack but there's likely a different line of code that I can put in its own sub to trick VB Editor to open that designer window back up again.

Any ideas?
