Hi,
I have created a flow wherein a new excel file gets created on SharePoint, every time the flow is run.
The file name being 'Output_Jan_2024' and once the file has been created, the next time flow will only update the file, till Jan ends.
At the start of next month, a new file has to be created('Output_Feb_2024') and same file gets updated till Feb ends and so on.
I have created the below flow so far:

Recurrence: scheduled to run daily
File Content: ‘Compose’ action to capture the output of a new excel file.
Create File: gets the output of ‘File content’ to create an excel file.

Create Table: Format as table
What action do I need to add to capture, if the folder already has the current month file, update the same file, else create a new?
Thanks.
