apache slign sitemap oak index

To use ootb functionality to generate sitemap using apache sling module should I create some oak indexes?

Right now only on demand option is working for me and scheduled generation only express itself in this warning

14.04.2022 16:20:00.120 *WARN* [sling-default-4-we-retail en-US Sitemaps] org.apache.jackrabbit.oak.query.QueryImpl Traversal query (query without index): select [jcr:path], [jcr:score], * from [nt:base] as a where [sling:sitemapRoot] = true and isdescendantnode(a, '/content/we-retail/global/en') option(index tag [slingSitemaps]) /* xpath: /jcr:root/content/we-retail/global/en//*[@sling:sitemapRoot=true] option(index tag slingSitemaps) */; consider creating an index

 Is there a suggested index that I should create to make it work?

I added this one with name as suggested

{
    "jcr:primaryType": "oak:QueryIndexDefinition",
    "compatVersion": 2,
    "includedPaths": [
         "/content/we-retail"
    ],
    "seed": -8084877133496368591,
    "type": "lucene",
    "async": [
        "async"
    ],
    "evaluatePathRestrictions": true,
    "reindex": false,
    "reindexCount": 3,
    "indexRules": {
        "jcr:primaryType": "nt:unstructured",
        "nt:base": {
            "jcr:primaryType": "nt:unstructured",
            "properties": {
                "jcr:primaryType": "nt:unstructured",
                "sitemapRoot": {
                    "jcr:primaryType": "nt:unstructured",
                    "propertyIndex": true,
                    "name": "sling:sitemapRoot"
                }
            }
        }
    }
}

 but nothing change 😞
