Our site has numerous sitemaps, and we are being billed quite heavily because the sitemaps cannot be generated statically. This is because, although our sitemap.ts files use generateSitemaps, they also require generateStaticParams to statically generate the multilingual paths. However, both of these functions cannot be used together because generateSitemaps just creates generateStaticParams behind the scenes, hence we can't prerender our pages. We have tried using these methods together and separately without success. Any ideas on how we can get a route like [locale]/app/sitemap.ts to build statically as a multi-split sitemap to reduce our Vercel bill will be greatly appreciated. Thank you
