I have build a React App which fetches a SharePoint Online list using Rest API. It basically does all the CRUD operations by sending requests to the API. In my SharePoint List, I have integrated Power Automate rule, when adding a new item, it should send an email notification to the person who has added it or created it. It works fine when I am doing it in the SharePoint Online list itself, but when I am doing it by my React App. I don't recieve any email notification.

Can anybody help me? what should I do? how to fix this?
