Save my email attachments to a SharePoint document library

When an email with an attachment arrives in the Inbox folder, save the attachment file in SharePoint document library. You can also use filter to run flow only for emails from a specific person by using the variable 'IsFromFilterApplied' set to 'true' and input expected 'From' Email Id in the condition to validate.
