How to display the UF_field of a blog post by post ID?

Question

1C-Bitrix

Good afternoon!
Tell me how to display the value of the UF_property of the BLOG_POST entity?
In custom fields, this property is already "hardwired", but I can't find information on how to work with BLOG_POST and posts, unlike methods for working with the catalog and sections.
So, given the Blog, there is a post in it, this post has a UF_property, so it would be displayed by the post ID.
Thank you.
