How to issue a token on behalf of the user?

How to issue a token on behalf of a user? in my case, the user needs to authorize his own resources to another user, similar to the UMA protocol.

That is not possible with ORY Hydra - we recommend using another method such as an API Key instead.

Sorry to hear that conclusion, but I’m curious, how do we implement UMA through ORY? Is it possible to modify your source code to implement the requirements I mentioned above? Is it complicated?

I don’t know what UMA is or how it works unfortunately, so I can’t really answer your question unless provided more details.
