Group by month or week with Laravel eloquent

Question

I have a project that has managed my investments, that is, it takes my daily statement and saved in my project so that I can see how much it is yielding, in short I have a table that are daily these values, I can already generate the information separately per day and it works perfectly (in fact it is a little more complex than that what I do but the basis is this);

However now it is getting bad to visualize when I caught a date range very large for example 1 year, it lists every day, I wanted a way to be able to group by month or week,

Thanks in advance for any help.

        $rows =  AtivosExtrato::select('titulo_id', DB::raw('SUM(valor_bruto_atual) AS valor'), 'data_imports.data_import as created_at')
        ->join('titulos','titulo_id', '=', 'titulos.id' )
        ->join('representantes','representante_id', '=', 'representantes.id' )
        ->join('data_imports','data_import_id', '=', 'data_imports.id' )
        ->where('user_id', Auth::user()->id) 
        ->whereBetween('data_imports.data_import', [$request->input('start_date'), $request->input('end_date')])
        ->groupBy('titulos.nome_titulo')
        ->groupBy('data_imports.data_import')
        ->orderBy('data_import')
        ->orderBy('titulos.nome_titulo')
        ->get();   

Briefly explaining what each eloquent information is:

Ativosextrate: the model where the daily income information is located;

1) Join: foreign table for securities names

2) Join: foreign table for the broker name

3) John: table that saves the date of import and relates to the id in the table of activesExtrato, it has function to reduce the weight at the time of the searches and gain performance.

Where: limiting the user in question

Wherebetween: limiting to the date range

1) groupBy: Grouping by titles

2) groupBy: grouping by the date of import
