I have made An App part using Napa in outlook365 which shows one URL of my external Application which I have made with that the current user name is there as in pic no.1{Devlopement code successfully Made}
Now I have made another outlook account in which SharePoint will open through office 365 which will be of End-user.I need to give some rights in such a way when user Open his SharePoint in outlook 365 on Main page the above App part will open with his name and above URL.I need to give some rights or permission so that his dashboard on login show that App part.
I don't know how to connect the above developer code with End user in such a way that App part will open in end user dashboard.
