not have property email

Hello! i am using '/reporting/feedback/details ’ endpoint of marketplace rest api . I have these properties {
“addonKey”: “xxxx”,
“addonVersion”: “xxxx”,
“applicationKey”: “jira”,
“hosting”: “Cloud”,
“date”: “2020-04-20”,
“feedbackType”: “uninstall”,
“reasonKey”: “interface”,
“fullName”: “yasemin dogan”
} , when i received as feedback notification email from marketplace, i can see the email of user who write the feedback on it but not on the '/reporting/feedback/details ’ endpoint. My question is how can i see email address of user between the properties of endpoint '/reporting/feedback/details ’ also ?
