This started as a question, but, since I solved the issue, it is now a discussion. As I was writing the question, I decided to try something new and eventually I got this working.
First of all, if the second monitor is not detected for some reason.
if the power connection is the same type as the connection to the docking hub device, try switching them.
Next, if the two displays are recognized but they are in reverse order such that the mouse disappears from one side of the monitor border and appears on the opposite side of the other display.
Don't waste time and just physically change the position of the physical displays.
