You can copy a file from SharePoint Online by using the Web activity to authenticate and grab the access token from SPO, then passing it to the subsequent Copy data activity to copy the file with the HTTP connector as the source.

Follow the prerequisites to create AAD application and grant permission to SharePoint Online.
