Custom visual aggregated dataViews values

Hi,

I'm making a custom visual in a dashboard connected to an Excel spreadsheet.

I just want to fetch distinct values from a column, but my values are always aggregated no matter which dataViewMapping type i use, and i don't want that.

For a column who contains (1, 1, 2, 2, 3, 3) i get [1, 2, 3] in my dataViews.

I want to get all the values keeping doubles.

For now here is my capabilites.json, simple as hell.

I already tryied other mapping types like categorical and others ...

Am i doing something wrong here ?

{
"dataRoles": [
        {
"displayName": "Values",
"name": "values",
"kind": "GroupingOrMeasure"
        }
    ],
"dataViewMappings": [
        {
"table": {
"rows": {
"for": {
"in": "values"
                    }
                }
            }
        }
    ]
} 

I already tryied to modify "column values type" in "Request editor" pannel in PowerBI Desktop to differents values to get this "Don't summarize" option, but that does not affect the data i get.

Does someone knows how to do what i want ?

Thanks.
