AEM apache sling sitemap generator is generating sitemap for author but not generating sitemap index.
I am able to successfully generate sitemap for config.author.

I have following configuration in config.author.local

However, sitemap-index is not getting generated.
I also have following content in filter.any
## Allow AEM sitemaps
/0073 { /type "allow" /path "/content/*" /selectors '(sitemap-index|sitemap)' /extension "xml" }
Rewrite rules
# allow sitemap access
RewriteCond %{REQUEST_URI} ((sitemap-index|sitemap).xml)$
RewriteRule ^(.+)\/?$ ${lc:$1} [PT,L]
Could someone please help on how to generate sitemap-index. I thought it is automatically taken care of
