Como obter os dados de DAU e MAU separadamente?

Sim, você pode usar o relatório de Visitas de Usuários para calcular o MAU.

A consulta abaixo detalha o DAU, MAU e a Porcentagem. Espero que ajude.

--[params]
-- date :start_date = 2021-01-01
-- date :end_date = 2022-01-01


WITH dau AS (
SELECT date_trunc('day', user_visits.visited_at)::DATE AS date,
       count(distinct user_visits.user_id) AS dau
FROM user_visits
WHERE user_visits.visited_at::DATE BETWEEN :start_date AND :end_date
GROUP BY date_trunc('day', user_visits.visited_at)::DATE
ORDER BY date_trunc('day', user_visits.visited_at)::DATE
),

data AS (SELECT
    date,
    dau,
    (SELECT count(distinct user_visits.user_id)
      FROM user_visits
      WHERE user_visits.visited_at::DATE BETWEEN dau.date - 29 AND dau.date
    ) AS mau
FROM dau)

SELECT
    date "day",
    dau,
    mau,
    ROUND((dau/mau::numeric)*100,2)||'%'  AS Percent
FROM DATA
