How do I filter and download only xlsx attachments from a Gmail node?

Hi all,

I need help with downloading a file from a Gmail node. I have multiple attachments in my emails, but I only want to download the ones with the xlsx extension. For example, in the image below there are 4 files (though the number could vary), and I’d like to filter out everything except the xlsx files.

How can I achieve this?
