What does "Configure your shared drives" mean?

I wanted to use AWS SAM CLI and installed Docker using the following URL.

However, I couldn’t figure out what exactly I need to do at “Windows > Configure your shared drives”. Can someone please tell me what I need to do for this?

It probably refers to sharing folders of the Windows host with Docker Desktop. You still need to allow Docker Desktop to read specific folders on macOS and If you are using the HyperV backend for “Docker Desktop for Windows” that my still be required. I don’t remember to be honest. All I know is that the folder sharing settings are not in Docker Desktop anymore. Probably because WSL2 can already read your host filesystem and you don’t need to manually allow Docker Desktop to read them.
