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.
