Screen broken, laptop connected to TV. Help with windows 11.

-
My laptop screen is broken. It seems the LED fluid or something has leaked due to hard pressing. That is inconsequential. I have it hooked up to my TV as an external monitor, however, it only displays what is on the screen once it reaches the Lock screen. I recently installed Windows 11, But I can’t even see the setup and I don’t know how to get through it to get to the Lock screen. Does anyone have a step-by-step with pictures or something to show me what happens once you install Windows 11 on a Lenovo laptop. I can occasionally make out the words ‘Undoing changes made to your computer’ or something akin to that. Thank you for your time.
