To get the mail with the above filters use the below code.
GraphServiceClient graphClient = new GraphServiceClient( authProvider );
var messages = await graphClient.Users[shivam1@m365x******.onmicrosoft.com].MailFolders["Inbox"].Messages
.Request()
.Filter("from/emailAddress/address eq 'DiegoS@M365x*******.OnMicrosoft.com' and subject eq 'Notify service to lookup new mail'")
.GetAsync();
As you can see, I am able to get the desired result using this same graph API.
Hope this helps.
