The list of post comments should be retrieved by a separate request, calling getPostComments query. The query returns the list of comments related to the given post with the pagination and possibility to change the order (default sorting is by the creation date, ascending). The following arguments can be used in the query:

beforeCursorReturns results that come before the specified cursor. Should be used together with last parameter. Cannot be used if after is set.—
firstIntegerReturns up to the first N elements from the list. Required if after parameter is set. Cannot be used together with last.—
lastIntegerReturns up to the first N elements from the list. Required if before parameter is set. Cannot be used together with first.—
reverseBooleanAllows to change the order of the sorting to DESC.FALSE
