flow designer - How to use subflow outputs in flow script

[TT3]

I have a flow and that calls another subflow for processing. Down the flow I want to access output from subflow in a flow script (instead of using Data Pill picker).

I tried fd_data.subflow_outputs.<variable_name> but that gave me an error - "Unsupported reference: subflow_output (from fd_data.subflow_output.callers_number)"

Thank you.

Access the subflow output in Flow script like fd_data.<subflow>.outputvariablename

fd_data._<step>__<flow_name>.outputvariable. Please refer to the screenshot for reference.
