How can we pass parameters from parent to child workflow?
In the child workflow, define parameter/variables to receive values from the parent workflow fields. In the parent workflow, you can fetch these variables in the Workflow Executor step and map them to fields in the parent workflow to fetch values or provide static values.
Inherit all variables from the workflow checkbox to pass all workflow parameters to the specified child workflow. You call them in the child workflow by putting them in curly braces and prepending with a $ sign.
