Cannot Use Click Toolbar Button Activity On SAP Popup

Click Toolbar Button activity cannot interact with a pop-up spawned by SAP GUI (regardless of the SAP GUI version). Error message reads: "This control does not support Click Toolbar Button activity".

Error message:

Root Cause: This behavior occurs because that pop-up is not accessible for automation.

Resolution: In order to fix this, use the Click Toolbar Button activity with this element (the one marked in a black square), and not the pop-up.
