Retrieving Comments using name

[Brotakuu]

If i have the name of a listing such as t3_85ahch in askreddit, how can i retrieve all comments for that listing?

Tried something like this, but not working.

session.subreddit('awardtravel').submission(from_id: "t3_85ahch").comments
NoMethodError: undefined method `from_id' for #<Redd::Models::Listing:0x0>

try something like this session.from_ids(["t3_85ahch"]). does it work?
