How to implement a search directory that includes the directory itself.
For example, using find can operate

find ./ -type d

will list all directories under the current directory (including the directory itself), but fd cannot.
The operation steps are as follows
Fd - td '.' ./

This operation only lists all subdirectories under the current directory and does not include itself. How to solve this problem
