Hello, I have a working power automate flow that when I receive an email from a certain mail, I add the file to a sharepoint folder, but when a new one arrives the other one is overwritten, now for one of my objectives that is okay. But for another objective I want to store the history of what I receive, so If i want to add the csv file to the already existing csv file in the sharepoint folder. Such that overtime the file keeps increasing incrementally with new information. So far i Have this.

But now instead it should look if the file already exists and add to it.
