Draw security pattern using usb c to hub with hdmi

Not sure if it's a note 10 issue or an android issue. My note 10 screen no longer works. I connect it to usb c to usb hub with hdmi. The monitor now shows clock and lock. The time is correct. I press the buttons on my wireless mouse and move it around but no lock screen pattern. With my note 9 I pressed the page up button and was able to see home screen. Samsung says the phone needs to confirm on the screen. Note 9 did not do that. Another rep say its a power issue again the time is correct. They don't have a correct answer for me. Another says older phones showed lock pattern on monitor and new ones don't. I seen youtube videos of people accessing the lock screen on monitor. They just draw the pattern using mouse. How do I move from the clock and lock icon to the lock pattern draw screen?
