How to use InferenceGraph with multi model backend?

[Strasser-Pablo]

I have tried to use inference graph functionality. However, I have not found in the doc where to indicate the name of the model.
In case of multi model backend e.g triton we need to model name to create the correct query. Is there a way to do that?
Currently, I receive the following error message:
{"error":"Request for unknown model: 'bigearthnet3' is not found"}
Which is true because bigearthnet3 is the name of the inferenceservice but not the model in it.
