Zammad as oauth identity provider


I read about the possibility to use Zammad as an identity provider: (API - Add allowed origin on self-hosted Zammad Server - #7 by thorsteneckel)

And found the option to add applications in the configurations /#system/api

But I couldn’t find any doc elaborating on this further (e.g. how to set App-ID and secret, which endpoints exactly to call to receive a token etc.)

Does anyone have any idea where I find information to get into it a bit further?

(Use case: I would like to use an authentication in a little external webapp which has no data-backend, i.e. without having to set up an extra user database/identitiy provider… In the future I want to implement various ways to interact via the zammad api from there but for a start I want to realize the user administration with zammad).

Thanks a lot
