I am using group nodes (input and output). But export in blender3.4 GLTF file.The ambient occlution file doesn't export with gltf file.

enter image description here

enter image description here

This Ambient occlution texture connect to GLTF Material output (group node) node. It shows the Ambient occlution map in Three.js editor.

I added those all nodes and ambient occlution map also then I export the model as GLTF file. Then I import the same model into the blender again those nodes are deleted automatically.

Taking as a reference your posted images links and node names, what worked for me was connecting the "Color" output from the "OCCLUSION" texture node directly to the "Occlusion" input from the "glTF Material Output" node, also I had a "Principled BSDF" node with many texture connections including albedo, emission, normal, roughness and metallic.

Maybe the inclusion of the roughness and metallic textures are important? I am not so sure. But when I exported the model from Blender as glTF 2.0 I chose under Format: "glTF Separate". When the export ended, it generated various textures, including a combined texture of 3 channels (RGB) with Ambient Occlusion (Red channel), Roughness (Green channel) and Metallic (Blue channel).
