THANKS @usayamadx ! Awesome.
I, too, had something that prevented the download. I put it in a blob and it works great:

// init
let xhr = new XMLHttpRequest()
let domain = 'https://read.amazon.com/'
let items = []
let csvData = ""

const formatBook = item => '"' + item.asin + '","' + item.title + '","' + (item.authors || [])[0] + '"\n';

// function
function getItemsList(paginationToken = null) {
let url = domain + 'kindle-library/search?query=&libraryType=BOOKS' + ( paginationToken ? '&paginationToken=' + paginationToken : '' ) + '&sortType=recency&querySize=50'
xhr.open('GET', url, false)
xhr.send()
}

// request result
xhr.onreadystatechange = function() {
switch ( xhr.readyState ) {
case 0:
console.log('uninitialized')
break
case 1:
console.log('loading...')
break
case 4:
if(xhr.status == 200) {
let data = xhr.responseText
data = JSON.parse(data)
if(data.itemsList) {
items.push(...data.itemsList)
}
if(data.paginationToken) {
getItemsList(data.paginationToken)
}
} else {
console.log('Failed')
}
break
}
}

// action
getItemsList()

// to csv
items.forEach(item => {
csvData += formatBook(item);
})
const blobCSV = new Blob([csvData], {type: 'text/plain;charset=utf-8'});
blobURL = URL.createObjectURL(blobCSV);
window.location = blobURL;
