How to actually use os-backup-api

[flushell]

I want to use the plugin os-backup-api, but I found a complete absence of documentation how to actually use it. I did find this, but I cannot find where to configure "key" and "secret" anywhere in the GUI. Is there any GUI element? Am I overlooking something? The documentation found here is not very helpful either. The "info" of the plugin is not helpful either, stating

Provide the functionality to download the config.xml

Can anyone point me in the right direction?

You go to System : Access : Users, choose your user, add an API key. It will download a files with key:secret :)

Thanks.
Had to give the user special rights for backup too.
Works now.

Would be nice if this was documented.

It is both, but in different places in the docs.
