New to botpress from MC. I have a flow(main) in which I have collected my user inputs as variables A B C. I now want to trigger a new flow flow2 which takes A B C as input variables and write them to say Google Sheets. Question : How do i feed in A B C into flow2 ?? I cannot hardcode values for A B C as they are driven by what the user inputs. thanks !!! I cannot see any documentation about this
