How to click on a third-party UI element in Adobe Illustrator

I have a third-party extension installed In Adobe Illustrator ("Overlord"). I use it all the time and would love to be able to trigger its buttons using Soundflow triggers. I contacted the developer and they said that the UI elements are not currently accessible as variable names due to some layering/obscuring in the way Adobe handles shell application and the plugins.

Only the full window is available when I try to "click UI element" from the SF actions.

How can I trigger one of these buttons? Is the only method using "relative position "? My screen changes a fair amount over time as the project evolves. I guess I might need to find a place onscreen to keep the tab in a fixed position.
