Models and datasets for Synthetic Data Augmentation for Zero-Shot Cross-Lingual Question Answering?

Source code for [this paper](https://aclanthology.org/2021.emnlp-main.562/) led me to [this page](https://paperswithcode.com/paper/synthetic-data-augmentation-for-zero-shot). I was redirected to this github repo but I am not able to find models and datasets proposed in that paper. I am looking for translated SQuAD. 

Can somebody help? Paperswithcode has erroneously linked this repo to that paper?
