MIDAS MRA dataset

Hello, I came across several papers (e.g., https://www.sciencedirect.com/science/article/pii/S0925231219315358) referring to the MIDAS dataset with the following link:

However, the link is broken, and I was unable to find the dataset on the internet. Could you kindly let me know where I can download the dataset?
