Here's a picture of the UI for the download, with 123 different "Download" buttons. https://twitter.com/nelson/status/1503848290193862658

I did an Amazon download too, after Amazon's subsidiary Goodreads lost all my data of 9 years. I'm grateful for how the GDPR and the CCPA mandate that companies provide data downloads. Amazon is clearly doing the bare minimum to comply. Other companies do more; Twitter's data download comes with a fully working offline Javascript app for reading and searching your tweets!
