Как парсить JSON с помощью GSON?

Есть JSON-чик, который надо запарсить - https://api.openweathermap.org/data/2.5/weather?q=Тюмень&appid=83623663100b56b2e64fa7b514835b7f&units=metric:

{"coord":{"lon":65.5272,"lat":57.1522},

"weather":
    [{"id":620,"main":"Snow","description":"light shower snow","icon":"13d"}],

"base":"stations","main":
    {"temp":-3.28,"feels_like":-10.2,"temp_min":-3.28,"temp_max":-2.95,"pressure":1006,"humidity":86},

"visibility":9000,

"wind":{"speed":7.15,"deg":80,"gust":12.07},

"clouds":
    {"all":100},

"dt":1698652392,

"sys":
    {"type":2,"id":2086898,"country":"RU","sunrise":1698633772,"sunset":1698667206},

"timezone":18000,

"id":1488754,

"name":"Tyumen",

"cod":200}

Надо достать из "main": "temp", "temp_min", "temp_max"

Код MainActivity:

package com.example.learnkotlin

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.TextView

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val temperature: TextView = findViewById(R.id.temperature)
        val minTemperature: TextView = findViewById(R.id.min_temperature)
        val maxTemperature: TextView = findViewById(R.id.max_temperature)

        val response: Response = com.google.gson.Gson().fromJson(
            "https://api.openweathermap.org/data/2.5/weather?q=Тюмень&appid=83623663100b56b2e64fa7b514835b7f&units=metric",
            object : com.google.gson.reflect.TypeToken<Response>() {}.type
        )
        temperature.text = response.main.temp
        minTemperature.text = response.main.temp_min
        maxTemperature.text = response.main.temp_max
    }
}

class Response(
    val main: Main,
)

class Main(
    val temp: String,
    val temp_min: String,
    val temp_max: String,
)

Приложение вылетает при запуске, библиотеку Gson в Gradle прописал.\

Код build.gradle.kts:

plugins {
    id("com.android.application")
    id("org.jetbrains.kotlin.android")
}

android {
    namespace = "com.example.learnkotlin"
    compileSdk = 34

    defaultConfig {
        applicationId = "com.example.learnkotlin"
        minSdk = 24
        targetSdk = 0
        versionCode = 1
        versionName = "1.0"

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            isMinifyEnabled = false
            proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
        }
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = "1.8"
    }
}
