Could not find :ARPresto:. Required by: project :unityLibrary Search in build.gradle files

I am currently integrating a Unity AR project as a library in a native Android Studio project. It is all fine with the exception that when I try to build/run the project in Android Studio I get the exception from the title:

Could not find :ARPresto:.
Required by:
    project :unityLibrary
Search in build.gradle files

I have no idea why this happens since the unity project seems to be successfully integrated as a library and I can open in the in Android Studio project menu.

This is the build.gradle file of the Unity Library:

    allprojects {
    buildscript {
        repositories {
            google()
            flatDir {
                dirs "${project(':unityLibrary').projectDir}/libs"
            }

        }
    }
}

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

apply plugin: 'com.android.library'


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation(name: 'ARPresto', ext:'aar')
    implementation(name: 'unityandroidpermissions', ext:'aar')
    implementation(name: 'VuforiaEngine', ext:'aar')

}

android {
    compileSdkVersion 31
    buildToolsVersion '30.0.3'

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    defaultConfig {
        minSdkVersion 26
        targetSdkVersion 31
        ndk { abiFilters 'armeabi-v7a' }
        ndk {
            // Default ABI list for this app, can be over-ridden by providing an abiList property
            // e.g. gradle -PabiList=x86 clean assembleDebug
            abiFilters ((project.findProperty('abiList') ?: 'armeabi-v7a, arm64-v8a').split(/,\s*/))
        }
        versionCode 1
        versionName '0.1'
        consumerProguardFiles 'proguard-unity.txt'
    }

    lintOptions {
        abortOnError false
    }

    aaptOptions {
        noCompress = ['.ress', '.resource', '.obb'] + unityStreamingAssets.tokenize(', ')
        ignoreAssetsPattern = "!.svn:!.git:!.ds_store:!*.scc:.*:!CVS:!thumbs.db:!picasa.ini:!*~"
    }

    packagingOptions {
        doNotStrip '*/armeabi-v7a/*.so'
    }
}

This is the module and project gradle files of the parent android app:

        google()
        mavenCentral()
//        flatDir {
