Check "Import-Export:glTF 2.0 format" in "User Preferences> Add-ons" to update and enable Adon.

PBR material settings

Since there is "glTF2.blend" in the "pbr_node" of the data downloaded from GitHub, select "File> Link> glTF2.blend". If you select "Node Tree> glTF Metallic Roughness" in it, glTF Metallic Roughness will be available in the note editor.

GlTF Metallic Roughness is added in "Add> Group" of the node editor. If you want to set the material color, set the color of BaseColorFactor. If you want to set texture, connect Image Texture to Base Color.
