NVIDIA JETSON XAVIER NX installation with sdkmanager 2.1

i installed using the sdk manager 2.1.0 the jetpack version 5.1.2 and i opted the option Download now, Install later., now i have completed the installation of sdk manager. Now how do i install those packages?
I couldn’t find them in the written folder.

Are you telling to flash the board or install the SDK? Or you don’t know what I mean here?

Install the sdk

You still need to use sdkmanager to install it. It does not send to your Jetson.
