Save Gmail attachment to Google Drive Or OneDrive

What are you trying to achieve?

I want to save Gmail attachment to Google Drive Or Microsoft OneDrive. I receive approximately 50 attachments per day from few KB to 5 MB. I see a video on how to do it but I am not clear on which paid plan will work for me in terms of if I want it to run every 5 minutes (# of ops?) and the total MB of files saved? Any guidance is appreciated.

Steps taken so far
