Calculate Weekly totals and should appear immediately after the corresponding week's data

Question

I have a data like below

contact_date	count	values
06/01/2023	230	0
06/02/2023	100	0
06/03/2023	200	0
06/04/2023	250	0
06/05/2023	120	0
06/06/2023	120	0
06/07/2023	200	0
06/08/2023	2230	0
06/09/2023	2310	0
06/10/2023	30	0
06/11/2023	300	0
06/12/2023	100	0
06/13/2023	120	0
06/14/2023	790	0
06/15/2023	900	0

and I want to calculate the weekly totals for the count and values and display the weekly total right after week. Weeks start Sunday and ends on Saturday. technically it should look like below

contact_date	count	values
06/01/2023	230	0
06/02/2023	100	0
06/03/2023	200	0
Weektot	530	0
06/04/2023	250	0
06/05/2023	120	0
06/06/2023	120	0
06/07/2023	200	0
06/08/2023	2230	0
06/09/2023	2310	0
Weektot	5260	0
06/10/2023	30	0
06/11/2023	300	0
06/12/2023	100	0
06/13/2023	120	0
06/14/2023	790	0
06/15/2023	900	0
Weektot	value	0

Here is the code I have written, I was able to calculate at the weekly level but I am not able to order it correctly. All the week data is appending at the end of the result

WITH WeeklyData AS (
    SELECT
        contact_date,
        count,
        values,
        DATEPART(WEEK, contact_date) AS week_number
    FROM table
)

SELECT
    contact_date,
    count,
    values
FROM WeeklyData
UNION ALL
SELECT
    'Week',
    SUM(count),
    SUM(values)
FROM WeeklyData
GROUP BY week_number
ORDER BY contact_date;
