Text Orientation via code

Hello, I'm working with CorelDRAW X8 and a VB application.

No issues launching Corel from VB, creating objects, etc.

However, I need to set the text orientation to Vertical in a shape I create via code.

I'm using the CreateArtisticText method from: https://community.coreldraw.com/sdk/api/draw/22.1/m/layer.createartistictext

And that works, but I cannot find a way to set the orientation.

I tried recording a Macro in Corel itself, but when I change the orientation of the text it says: Recording of this command is not supported.

I've been looking in the SDK, but cannot find a property/method to do it.

Any idea if it's available somewhere?

Thank you!
