Access Google Photos API with Kotlin/Java

Question

I am trying to connect my program with the google photos API. I need that in case to make CRUD operations with google photos API.

I tried doing it with the example code from google photos API documentation:

// Set up the Photos Library Client that interacts with the API
PhotosLibrarySettings settings =
     PhotosLibrarySettings.newBuilder()
    .setCredentialsProvider(
        FixedCredentialsProvider.create(/* Add credentials here. */)) 
    .build();

try (PhotosLibraryClient photosLibraryClient =
    PhotosLibraryClient.initialize(settings)) {

    // Create a new Album  with at title
    Album createdAlbum = photosLibraryClient.createAlbum("My Album");

    // Get some properties from the album, such as its ID and product URL
    String id = album.getId();
    String url = album.getProductUrl();

} catch (ApiException e) {
    // Error during album creation
}

I am creating the credentials from Google Cloud Platform. When i am doing it with the Service Account credentials, it says 'PERMISSION DENIED: Service accounts are not supported'. I also tried using OAuth 2.0 client, but there is again a mistake - there is not a type field in the json credentials file.

I also read Access google photos API via Java stackoverflow question and tried with that sample code:

UserCredentials.newBuilder()
        .setClientId("your client id")
        .setClientSecret("your client secret")
        .setAccessToken("Access Token")
        .build()

Here the problem is that I couldn't create access token. I saw Integrate Google Photos Library API in android application Kogi eric's answer who creates access token with this code:

val client = OkHttpClient()
            val requestBody = FormEncodingBuilder()
                    .add("grant_type", "authorization_code")
                    .add("client_id", "")
                    .add("client_secret", "")
                    .add("redirect_uri", "")
                    .add("code", "yourweb server id)
                    .build()
            val request = Request.Builder()
                    .url("https://www.googleapis.com/oauth2/v4/token")
                    .post(requestBody)
                    .build()
            client.newCall(request).enqueue(object : Callback {
                override fun onFailure(request: Request, e: IOException) {

                }

                @Throws(IOException::class)
                override fun onResponse(response: Response) {
                    try {
                        val jsonObject = JSONObject(response.body().string())

                        mTokenExpired = SystemClock.elapsedRealtime() + jsonObject.optLong("expires_in") * 1000

                        accessTokenObservable.postValue(Resource.success("",jsonObject.optString("access_token")))


                    } catch (e: JSONException) {
                        e.printStackTrace()
                    }

                }
            })

but idk what to type in these fields:

.add("grant_type", "authorization_code")
                    .add("client_id", "")
                    .add("client_secret", "")
                    .add("redirect_uri", "")
                    .add("code", "yourweb server id)

Thanks!
