Get value out of the Vars type

Hey short question regarding Workflows. I send Formdata to my Workflow via Integration Endpoint. After reading the data, my Variable regData looks like this:
“regData”: {
“adresse”: {
@value”: “Musterstraße 12, 12345 Musterstadt”,
@type”: “String”
},
“country”: {
@value”: “DE”,
@type”: “String”
},
“dynastieName”: {
@value”: “Test Systems”,
@type”: “String”
},
“ecoId”: {
@value”: “DE-1234567”,
@type”: “String”
},
“foundingDate”: {
@value”: “2020-05-18”,
@type”: “String”
},
“orgaName”: {
@value”: “Test GmbH”,
@type”: “String”
},
“plz”: {
@value”: “12345”,
@type”: “String”
},
“rechtsform”: {
@value”: “GmbH”,
@type”: “String”
},
“sector”: {
@value”: “IT-Services”,
@type”: “String”
},
“steuerId”: {
@value”: “123/456/78901”,
@type”: “String”
},
“ustId”: {
@value”: “DE123456789”,
@type”: “String”
}
},

How am I able to take the value of e.g. country and assign it to a variable. regData.country results in empty object, regData.country.value gives an error.

What am I missing here?
