Where are the convox v3 CLI settings stored?

The convox gen 2 CLI stored settings under a ~/.convox directory, such as ~/.convox/auth, ~/.convox/rack, and ~/.convox/host. It appears that these files are no longer used for Convox v3 CLI. However, it looks like <project>/.convox/app is still used so I can configure the app name for each project.

Did the ~/.convox directory get moved somewhere else on Mac?
