Help. Postman has built-in random variables (For Example $randomInt, $randomNamePrefix). How can I use them in mutations? I'm using $randomNamePrefix - this does not work unfortunately. 

mutation SaveOrderOutInput {
saveOrderOut (input: {fio: {firstName: $randomNamePrefix, lastName: "Ivanovd", middleName: "Loshdya"}, address: {postIndex: "43434", city: "Kolyama", address: "Koko d.5 oe. 3"}, passport: {citizenship: "Ангола", passportId: "3265 748742", passportAuthority: "Ufms Ksd Jw pfd", passportIssueDate: "01/07/2000"}}){
ok
orderOut {
  id
  firstName
  middleName
  lastName
  postIndex
  city
  address
  citizenship
  passportId
  passportAuthority
  passportIssueDate
}
    clientMutationId
 }
}
graphql postman

Encapsulate in 

{{$$randomNamePrefix}}

So it will be

mutation SaveOrderOutInput {
saveOrderOut (input: {fio: {firstName: {{$randomNamePrefix}}, lastName: "Ivanovd", 
middleName: "Loshdya"}, address: {postIndex: "43434", city: "Kolyama", address: "Koko d.5 oe. 3"}, passport: {citizenship: "Ангола", passportId: "3265 748742", 
passportAuthority: "Ufms Ksd Jw pfd", passportIssueDate: "01/07/2000"}}){
ok
orderOut {
 id
 firstName
 middleName
 lastName
 postIndex
 city
 address
 citizenship
 passportId
 passportAuthority
 passportIssueDate
}
clientMutationId
}
}
