I'm trying to use Power Automate to access a SharePoint Online list and am getting an error. This is the first flow we have created since launching SPO. I verified my account has permissions to access the list from within SharePoint. However if I try creating a flow from powerautomate.microsoft.com or from within SharePoint using the "Integrate/Power Automate" menu, I get the same results. Whenever I try to run the flow I get the following error:
error: status 403 "Attempted to perform an unauthorized operation."
Is there something I need to do in SharePoint for it to allow it to be accessed with Power Automate?
