-- the maxdepth parameter does not work on my Mac notebook

[LJF2402901363]

Da when I use the command: "npx markdown-toc -- no-firsth1 -- bullets " * " --maxDepth 1 README.md" to generate the readme's directory, it is found that the generated directory has three layers, which is the same as the directory level of my readme.
This means -- the maxdepth parameter doesn't work on my Mac notebook, but the other parameters are fine.
What is the reason for this? Also, the readme directory of this project is very good-looking, what is its generation command?
