Does WSL2 docker need windows docker desktop?

Describe the solution you'd like
I tried to search some web page and found they teach you have to install windows docker desktop.
I confuse about it , because MS said WSL2 is based on Linux Core so it should not need windows desktop theoretically.

Docker Desktop WSL 2 backend | Docker Documentation said it need docker desktop but i can install and build docker in WSL2 with this script and there's no windows docker desktop.

$ curl -fsSL https://get.docker.com -o get-docker.sh
$ sudo sh get-docker.sh
$ sudo service docker start

Describe alternatives you've considered

Additional context

No you do not require Docker Desktop to use WSL 2. The only requirements for WSL 2 are that you:

• Have the right version of Windows installed
• Have the Virtual Machine Platform and Windows Subsystem for Linux optional components installed
