How to add users in azure devops through Postman REST API

I'm using collections (not organization) in azure devops and trying to add users in teams (under project settings) through Postman REST API.

I can retrieve teams details using PAT auth:

GET https://devops.company.com/tfs/COL/_apis/projects/My-WORK/teams?api-version=6.0

Success Response:

{
    "value": [
        {
            "id": "01xxccrayr-a443-600d-db0d-12435",
            "name": "MY-WORK Team",
            "url": "",
            "description": "team description",
            "identityUrl": "xxxx",
            "projectName": "MY-WORK",
            "projectId": "8540tuyfred-qawsd-fre432-fre3-57wedsa1546thyf"
        }
    ],
    "count": 1
}

but unable to add users into specific teams through Postman:

PUT https://devops.company.com/tfs/COL/_apis/GroupEntitlements/{teamID}/members/{memberId}?api-version=6.0

e.g. PUT https://devops.company.com/tfs/COL/_apis/GroupEntitlements/01xxccrayr-a443-600d-db0d-12435/members/anyemailid@not.com?api-version=6.0

Error Response:
