First of all, I installed the plugin of H3 in QGIS 3.22.16 Then I installed the library of h3 in Windows as explained in the tutorials for Python.
pip install h3
I got the successfully installed in PowerShell (and also uninstalled it and tried in VSCode) and then when I opened QGIS again nothing happened. I also tried downloading the script and opening it from QGIS processing tools but I keep getting the pop-up oh help for installing.
I'm using Python 3.8
