I am building a complex flow in Flow Designer, which requires sending a report CSV file upon completion. I already have code that creates comma separated lines (strings), so I was trying to build a file using that code and without a schema. That is, instead of using Begin File -> Append to Delimited File -> Build file, I would like to use Begin File -> Append to File... but now I am stuck because I am not seeing any action to close the file, which I expect to be needed. What should I do to close the file? I am comfortable with coding and can do a scripted action if needed, please share your thoughts / guidance.
