Problem getting VisioViewer to work in VBA

Hello, in Word, I would like to create a userform that allows the user to load and view a Visio drawing without that user either having Visio or Visio Viewer installed on their computer.

I added the Microsoft Visio Viewer 16.0 Type Library reference to my VBA project. I then added the Visio Document control to my project. I then inserted a "Viewer1" control to my userform. However, I cannot figure out how to load a .VSD file into the viewer. I cannot find any useful information on the Internet about this. This particular information (https://docs.microsoft.com/en-us/off...ut.programming) provides a code example for VB 6.0 but doesn't work in VBA.

Does anyone have any suggestions?
