I have code that writes when POST an excel file in the project directory for future referencing... i know databases exists but that's how the client wanted it lol the issue is of course since the service the files are ephiemeral on a redeploy they disappeared i attached a volume but tbh i have no idea on how to write to it

like i'm actually using

const excelDirPath = join(process.cwd(), 'excel');

const excelFilePath = join(excelDirPath, 'calc.xlsx');

and i mounted /excel in the volume does that automagically works or i have to adjust it?
