is there 'do' token (for format) in unicode token?

[Kanary159357]

https://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table
https://date-fns.org/v2.30.0/docs/Unicode-Tokens

In the documentation, it said that date-fns uses unicode token,
However, I couldn't find 'do' token symbol or field, but there are day of month convert code in date-fns. (1st, 2nd, 3rd.... 31st)

So I'm confused....

So it would be two case.

1. I didn't find the token documentation of 'Day of Month' (do) in Unicode Token Docs but it has.
2. There are no 'Day of Month' token but date-fns implements it

What is correct?

I know that o means ordinal indicator but, could not find the explaination on Unicode Token Docs...
