I'm trying to attach a file in an Outlook email instance that has been downloaded and saved to my files generated from the first part of this same flow. I don't know how to add this file as an attachment. I've tried creating a variable since the file name will change each time this flow is run. The file path part is the location and name of the file I'm trying to attach to the Outlook email.

I set my variable to 'RootPath' - is that right for what I'm trying to do?

Using 'Send email message through Outlook':

I've run my flow, and it will send the e-mail but no attachment.
I also thought about setting the clipboard text as the path+name of the file, but I can't figure out how to make that as an attachment in the Outlook instance. I get an error saying it must be 'list of files' or no error at all, just no attachment gets sent.
I plan on running this weekly, so what's the best way to attach files on the outlook email message? Ideally it attaches the most recent file that has been added to a specific folder.
