Solution.
New xhrHijacker:

xhrHijacker(function(xhr, id, origin, args) {
if(!initialied && origin === 'open')
//if(origin === 'open')
if(args[1].indexOf('/GetVodPlaybackResources') > -1 || args[1].indexOf('/GetPlaybackResources') > -1) {
init(args[1])
.catch(error => {
console.log(error);
alert(`subtitle downloader error: ${error.message}`);
});
}
});

New parseUrl:

function parseURL(url) {
if (url.includes("GetVodPlaybackResources")){
const urlObj = new URL(url);
const urlHostname = urlObj.hostname;
const deviceID = urlObj.searchParams.get("deviceID");
const deviceTypeID = urlObj.searchParams.get("deviceTypeID");
const marketplaceID = urlObj.searchParams.get("marketplaceID");
return `https://${urlHostname}/cdp/catalog/GetPlaybackResources?consumptionType=Streaming&desiredResources=CatalogMetadata%2CForcedNarratives%2CSubtitleUrls&deviceID=${deviceID}&deviceTypeID=${deviceTypeID}&firmware=1&gascEnabled=true&marketplaceID=${marketplaceID}&resourceUsage=CacheResources&videoMaterialType=Feature&operatingSystemName=Windows&operatingSystemVersion=10.0&titleDecorationScheme=primary-content&subtitleFormat=TTMLv2&uxLocale=en_US&asin=`;
} else if (url.includes("GetPlaybackResources")){
let filter = ['consumptionType', 'deviceID', 'deviceTypeID', 'firmware', 'gascEnabled', 'marketplaceID', 'userWatchSessionId', 'videoMaterialType', 'clientId', 'operatingSystemName', 'operatingSystemVersion', 'customerID', 'token'];
let urlParts = url.split('?');
let params = ['desiredResources=CatalogMetadata%2CSubtitleUrls%2CForcedNarratives'];
urlParts[1].split('&').forEach(function(param) {
let p = param.split('=');
if(filter.indexOf(p[0]) > -1)
params.push(param);
});
params.push('resourceUsage=CacheResources');
params.push('titleDecorationScheme=primary-content');
params.push('subtitleFormat=TTMLv2');
params.push('asin=');
urlParts[1] = params.join('&');
return urlParts.join('?');
}
}

After doing that, the option to download appear.

Does it work for you? Tried that command and it doesn't work for me.

Yes, it works.
Copy and paste new xhrHijacker and New parseUrl.
