How to create a CIM object from a JSON string via ArcPy？

Question

I use "arcpy. Cim. CIMSymbols. CIMCompositeCallout ()" creates a CIMCompositeCallout object, but it is missing a lot of properties, I want to create a CIMCompositeCallout object with full properties from a relevant JSON string and assign it to a layer. Is there a way?

I know one function is GetJSONForCIMObject, and I just want to know how to implement it in reverse.

Thank you in advance.

I agree, but I may not have a layer to copy its definition.

I've solved this problem for now by adding some properties to the definition.

Thanks for your reply.

Have you used the arcpy.mp CIM access module?  It makes pulling CIM definitions for a layer easy then you modify existing values or build a copy of that definition for a new layer.
