Check email for specific attachments once a month and only for the last month

Hi @MutedJam, thanks for the suggestion, I am trying it now and I am getting a Error 400: redirect_uri_mismatch (screenshot below). There were some problems with spaces getting pasted into the ID and secret fields, but I have checked those and they seem fine. Copied the redirect OAuth Redirect URL from the node and generated the ID and secret fine. Not sure if it is my OAuth Consent screen on Google that is the issue here. Still looking for answers on the documentation but no luck so far.

EDIT: Checking a solution posted here
