My Library (sideload) games are available to Argon subscribers. At this time (June 2022, sideloading is available on Nvidia Shield Android TV devices. Other Android TV boxes will be added as testing verifies.)

Argon > Settings > My Library

Select the folder that contains the files you want to add to Argon. Selecting the "Downloads" folder is not possible because of Android's Storage Access Framework security permissions. A folder and its subfolder inside Downloads or another folder can be selected.

Multiple folders can also be selected.

Finally, in the main UI, tap on the selection menu and select "From My Library"
