Does ComfyUI script includes ComfyUI-Manager?

ComfyUI-Manager : https://github.com/Comfy-Org/ComfyUI-Manager
Helps with installing Models that are missing from Comfy. I don't think it is included with the script. it would be great to included it or add a guide to help in adding it to the LXC. to avoid the following message when using Comfy
Missing Models
When loading the graph, the following models were not found
