Given a date dimension, how to calculate `business day into month` of this date dim?

I have a date dimension in a view, I can drill it down to

timeframes:[

raw,

date,

day,

week,

month,

quarter,

year,

]

I want to add business day into month, which gives me a number indicating nth business day of that month.

for example 2022-07-12 is 8th business day of July.
