Can I extract a 'built-in-function' node by using the 'named_modules' function?

Now, I’m trying to synthesize a node definition consisting of the ResNet-50 model.

The ResNet model has a ‘add’ node as a ‘built-in function’.

However, this ‘add’ node is not readable when I use the ‘named_modules’ function in the ResNet model.

Other functions like ‘modules()’, and ‘named_children’ are the same as well.

How can I extract the ‘built-in function’ node information by using the ‘named_modules’?

If my solution is wrong, please kindly let me know about that.
