Upgrading compose/gradle

Question

I copied project from GitHub and I want to modify it. But I can't add LazyHorizontalGrid so I guess I need to update Jetpack Compose version or Gradle right? What is proper way of doing that because if I do it with Project Structure as IDE suggest app crashes and I can't even build project. I googled error and then next one and then next one and so on. But I think that it shouldn't be so hard to just update project.

LazyHorizontalGrid was added with 1.2.0 of the Compose Foundation dependency.
To update just change your build.gradle files.

In the root build.gradle file:

buildscript {
    ext {
        compose_version = '1.2.1'
    }
    //..
    dependencies {
       //...
       classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10"

   }
}

In your app/build.gradle:

android {
    compileSdk 33
    //...
    composeOptions {
        kotlinCompilerExtensionVersion 1.3.1
        
    }
}

dependencies {
    implementation "androidx.compose.foundation:foundation:$compose_version"
    //...all the other compose dependencies
}
