Query to consolidate inline in dataview table and sum Time

Hello.. I need a help to make a table query using inline fields and consolidate per Date and Task and sum the time per activity.
By the way, English is not my language, sorry my mistakes…

I have the follow data in daily notes:

  • Day:: 2025-06-19

    • Time:: 00:35
    • Task:: Activity 2
  • Day:: 2025-06-19

    • Time:: 00:55
    • Task:: Activity 2
  • Day:: 2025-06-20

    • Time:: 00:40
    • Task:: Activity 3
  • Day:: 2025-06-21

    • Time:: 00:20
    • Task:: Activity 1
  • Day:: 2025-06-21

    • Time:: 00:30
    • Task:: Activity 2
  • Day:: 2025-06-21

    • Time:: 01:25
    • Task:: Activity 1

Things I have tried

I’ve tried this query with results:

TABLE WITHOUT ID item.Day, Task, Time
FLATTEN file.lists as item
FLATTEN filter(item.children, (c) => c.Task)[0].Task as Task
FLATTEN filter(item.children, (c) => c.Time)[0].Time as Time
WHERE item.Day
SORT Day

But, I’d like:

Same of Grouped by week, and summed:

TABLE sum(rows.cTime) as "Time", rows.cTask as "Tasks"
FLATTEN file.lists as item
FLATTEN filter(item.children, (c) => c.Time)[0].Time as cTime
FLATTEN filter(item.children, (c) => c.Task)[0].Task as cTask
WHERE item.Day
GROUP BY dateformat(item.Day, "WW") as Week

Pretended result:

Thanks for help!!!
