No compatibility with mkdocs-material-7.1.4

Hi,

I tried your code and it works fine.
On my project, I use mkdocs-material-7.1.4  but I don't know what I need to change on the customized theme.
I saw that you cutomized the file base.html and nav.html but I don't know really where or what I need to add or change some code.
Can you help me, please.

Best regard.
