In my Entity I have Column

  @Column({ type: 'jsonb', default: [] })
  solutionFormats: Array<SolutionFormats>;

where

export enum SolutionFormats {
  VIDEO = 'VIDEO',
  IMAGE = 'IMAGE',
  LATEX = 'LATEX',
}

I want to do grouping by values in this solutionFormats column and count results, i.e. if I have 2 rows whith solutionFormats being [LATEX, VIDEO], [LATEX], the output should be {LATEX: 2, VIDEO: 1}. How to do it? I have already a proplerly filtered queryBuilder object and I want to do this grouping on solutionFormats column.
