Hi, is there an easy to do function calling in workflows?

I followed the complete tutorial for workflows but I didn't find a function calling example.

This is the guide I followed. https://docs.llamaindex.ai/en/stable/module_guides/workflow/#workflows

I did find an example of function calling in Jupyter Notebooks but it contained a lot of low level/boilerplate code I really don't want to write everytime I want to do function calling in my workflows.

This is what I am referring to:
