MS Flow Manually Initiate an Outlook's Folder Attachments to Onedrive

I'm trying to take all the email attachments in one folder and copy them to a onedrive folder. I have seen the automate/flow that does it on new email messages that arrive in the inbox but not one I can initiate manually on a specific folder. I've tried to edit the one that works on new inbox mail but haven't gotten it to work. Any suggestions?
