struggle with conditional query

        {
          where: {
          id: { gte: cursor },
          mode: 0,
          userscore: input.displayOnlyUnplayedPredictions
            ? {
                none: {
                  // Ensures that no Userscore related to this Prediction has the cified osu_user_id
                  AND: [
                    {
                      osu_user_id: ctx.session.user.osu_user_id,
                    },
                    {
                      accuracy: {
                        gte: input.displayOnlyUnplayedBeatmapsWithAcuuracyAbove,
