{ "oldestFirst": false,

 "maxItems": 5,

 "startDate": "2021-05-11T22:30:00.000Z",

 "endDate": "2021-05-11T23:00:00.000Z"

You can try to use web site https://currentmillis.com/ to convert date to numeric milliseconds (like {"startDate":1620223200000, "endDate":1620743400000}), and pass the parameters as JSON in postman.

Moreover

This format I use from previous Topic
https://community.ptc.com/t5/ThingWorx-Developers/How-to-use-QueryNamedPropertyHistory-service-with-API-call/td-p/507484

So, i don't know the right format is in number or string like that
