Injecting Client Metadata into JWT using Ory Hydra

[resulbdev]

I am using the client_credentials flow in Ory Hydra. I have two questions regarding customizing the resulting JWT:

Is the Token Hook (Webhook) the only available method to inject custom claims into the Access Token JWT?

Why is the metadata provided when creating the client not automatically included in the JWT claims? Is there a configuration to enable this?

for client_credentials yes (since it doesn't use consent UI).

Why is the metadata provided when creating the client not automatically included in the JWT claims?

should it be? not sure about this part.

can you explain in more detail what the problem is you are trying to solve with client metadata? like what is your actual use case here?
