Return a count of ID by last Week Ending Date

[Haydn_R]

I'm currently using the following to return the weekending (Friday) for a column called "Request Date"

Week End Date Internal = format('Internal Requests'[Request Date] - WEEKDAY('Internal Requests'[Request Date],2)+5,"DD Mmmm YYYY")

 What I'd now like to do is do a count of the measure called "ID", that will give the the count of "ID" for the latest Week Ending.

Desire result below. 

Week End Date    ID
02-Dec-22           350

Table below mock up of data in a table. I have been suing PB for a couple of weeks, so any help is appreciated.

Week End     Date ID
18- Nov-22   987
25-Nov-22   500
02-Dec-22    350

@Haydn_R , week start sat, week end friday

Week Start date(Sat-Fri) = 'Date'[Date]+-1*if(WEEKDAY('Date'[Date])<7,WEEKDAY('Date'[Date]),WEEKDAY('Date'[Date])-7)Week End date(Sat-Fri) = 'Date'[Date]+-1*if(WEEKDAY('Date'[Date])<7,WEEKDAY('Date'[Date]),WEEKDAY('Date'[Date])-7) +6

in measure use max(Date[Date]) of maxx(allselected(date), Date[Date]) ot today
