I am trying to export an Android project from Unity to use XR in an Android application. When I copy the project over from Unity, I am unable to reference com.unity3d.player.IUnityPlayerLifecycleEvents. What am I doing wrong?

(app:)Build.Gradle.kts

plugins {
    alias(libs.plugins.android.application)

    namespace = "com.project.unitytest2"

        applicationId = "com.project.unitytest2"
        minSdk = 30
        targetSdk = 34
        versionCode = 1
        versionName = "1.0"

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
        vectorDrawables {
            useSupportLibrary = true
        }
    }

    buildTypes {
        release {
            isMinifyEnabled = false
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
        }
    }

    sourceSets {
        getByName("main") {
            jniLibs.srcDirs("src/main/jniLibs", "libs/unityLibrary/src/main/jniLibs")
        }
