Configure script fails to clone repository

When running `do ##class(SourceControl.Git.API).Configure()`, the user is prompted to provide an SSH key with this message:
> Path to private key file for SSH remotes; if file does not exist, later prompts will help set it up with proper ownership:

If I leave this blank and proceed to clone a repository, I am never prompted to create an SSH key through the script even though this text tells me I should expect that.

Is the SSK Key prompt referring to the GUI (where it sometimes provides a button to facilitate creating a key) or later in the Configure script? Best case is that this instruction just needs clarification. Worst case, this is a feature that is not working as intended.

(for what it's worth, when I first create an SSH key myself and configure the public part in github/bitbucket, the clone process works.)
