Failure to setup Room in build.grade

I'm trying to configure the build.grade to use Room

The error persists:

Unresolved reference: room

And, consequently, the anotation remains Unresolved

@Entity

After 7 tutorials and 3 days, I have to surrender and ask for help.

Here I paste my build.grade. I've got it from this google tutorial:

https://developer.android.com/codelabs/android-room-with-a-view-kotlin#3

Which, by the way, is completely diferent from this other google tutorial:

https://developer.android.com/training/data-storage/room

What am I doing wrong?

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'kotlin-kapt'

}

android {
    compileSdk 32

    defaultConfig {
        applicationId "com.firewalker.mouth_conjugation"
        minSdk 21
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {

        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }

Thanks to Mike T and Dkathayat1, it worked. I had to set the correct versions.

The code is the folowing:

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'kotlin-kapt'

}

android {
    compileSdk 32

    defaultConfig {
        applicationId "com.firewalker.mouth_conjugation"
        minSdk 21
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled 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'
    }

    packagingOptions {
        exclude 'META-INF/atomicfu.kotlin_module'
    }
