let jsonData = pm.response.json();
// use whatever key in the response contains the jwt you want to look into.  This example is using access_token
let jwtContents = jwt_decode(jsonData.access_token);

// Now you can set a postman variable with the value of a claim in the JWT
pm.variable.set("someClaim", jwtContents.payload.someClaim);
