metaData supplied to /api/login

[Moonshine]

When using the login api you can supply a metaData object with info like name, type, description. It says:

This meta data is used to describe the refresh token that may be generated for this login request.

Assuming refresh tokens are enabled for the app how is this information involved? Originally I assumed this data would be provided (and displayed) with the login records, but apparently it has a different use.

Thanks!
