I can't find TFT built in library in my Arduino IDE 1.8.19

when I search in Boards Manager with 'TFT', found nothing out, why?
Thanks
Adam

Why would a library be under Boards Manager?

here said it.

Please provide the exact timestamp in that video where it tells you to install the TFT library using the Boards Manager.

Play the video again. Do you actually hear the words DEVICE Manager?

GREAT!
thank you gfvalvo!
