Cannot find Integration

[nhimf]

The manuals says "The use of HACS is supported and is the preferred means of installing this integration."

But I cannot find the integration or add-on anywhere in my setup. Nothing pops up using "solis", "ginglong" or parts of those words. What do I need to look for?
While I can do the manual steps, I always prefer the assisted setups as they tend to less breakage.
