Filtering data from azure alerts in postman

I am using postman to collect triggered alerts from Microsoft azure, but I’m having trouble filtering the API in postman. Does anyone know how to filter the data, so that I only keep the data if isSuppressed is false? 90% of all the data I am collecting from the API has isSupressed true, but I am only interested in the cases where isSupressed is false. I have added two examples of elements from the API below (without the keys). The URL I am using looks like this: https://management.azure.com/{scope}/providers/Microsoft.AlertsManagement/alerts?api-version=2019-03-01

{
            "properties": {
                "essentials": {
                    "severity": "Sev0",
                    "signalType": "Log",
                    "alertState": "New",
                    "monitorCondition": "Fired",
                    "monitorService": "Log Analytics",
                    "actionStatus": {
                        "isSuppressed": true
                    },
                }
            },
        },

{
            "properties": {
                "essentials": {
                    "severity": "Sev0",
                    "signalType": "Log",
                    "alertState": "New",
                    "monitorCondition": "Fired",
                    "monitorService": "Log Analytics",
                    "actionStatus": {
                        "isSuppressed": false
                    },
                }
            },
        },
