Flambeau is missing file write permissions to provide exported csv

[zxiiro]

I'm trying to use Flambeau to export a CSV that I can import into Google Sheets but it seems it does not have permissions to create files in order to provide the CSV to me. (see attached image)

Anyway we can make this work? the data I'm trying to get from Flambeau is too large for it to print all the data into the chat window so being able to get a CSV file would be useful.
