App Search - Analytics always empty

Hi,

I have a fresh install of Elasticsearch/AppSearch/Kibana 7.17.1 on centos VM.

In Kibana, all works well, but analytics are always empty although I inserted documents with API.
I see fetch queries but all values are 0 :

{
    "allTags":[
        "All Analytics Tags"
    ],
    "analyticsUnavailable":false,
    "clicksPerDay":[
        0,
        0,
        0,
        0,
        0,
        0,
        0
    ],
    "currentTag":"All Analytics Tags",
    "endDate":"2022-05-10",
    "logRetentionSettings":{
        "enabled":true,
        "disabled_at":null,
        "retention_policy":{
            "is_default":true,
            "min_age_days":180
        }
    },
    "queriesNoResultsPerDay":[
        0,
        0,
        0,
        0,
        0,
        0,
        0
    ],
    "queriesPerDay":[
        0,
        0,
        0,
        0,
        0,
        0,
        0
    ],
    "recentQueries":[
        
    ],
    "startDate":"2022-05-04",
    "topQueries":[
        
    ],
    "topQueriesNoClicks":[
        
    ],
    "topQueriesNoResults":[
        
    ],
    "topQueriesWithClicks":[
        
    ],
    "totalClicks":0,
    "totalQueries":0,
    "totalQueriesNoResults":0
}

Maybe I forget to configure anything ?

Thank you in advance for your help
