Concat operator not supported (IDFGH-14774) (AIV-760)

[carolineys]

Is your feature request related to a problem?

When I attempted to deploy my .espdl model, I encountered the following error:

I (1078) dl::Model: net__model_1/model/lambda/stack_Concat__726: Concat

E (1078) dl::Model: Concat is not supported. Please implement and register it first.

Since the concat operator is supported by esp-ppq, I assumed that the list of supported operators would be the same. Is there any workaround if this concat operator is indeed not supported if I need to deploy this model?
Where can I find the list of operators supported by esp-idf?
