The Lightmap adjuster does show up in the tools (Unity 2019.1)

[ghost]

Hi, I might be just doing something wrong (not used to using packages in Unity), but the lightmap adjuster doesn't show up in the "Tools" tab after I've put the com.alexismorin.autolightmapadjuster directory in the Package directory of Unity (not sure if it's normal, but I can't drag and drop it and I can't import it via the Asset > Import Package > Custom Packages ; I had to place it via the Window File Explorer. After that it did show up in the Package Manager, but still nothing in the tools.
I have no idea what could cause this problem or how to solve it so if you know, would you please let me know ? Thanks!
Btw, this tool seesm absolutely amazing and it's a very good idea to create it. Very smart and useful! Good job and wish you the best.
