Can only get at most 20 relevant comments

[asheseux16]

Here is my code:

gen = fs.get_posts(
        post_urls = ["https://mbasic.facebook.com/" + fanpage + "/posts/" + '939460300875189'],
        options = {"comments": 30, "progress": True}
    )

post = next(gen)

comments = post['comments_full']

i = 0
for comment in comments:
    print(i)
    print(comment['comment_text'])
    print()
    i += 1

It returns at most 20 comments and they are all "relevant" ones but not "all comments". The kevinzg version succeeds in getting all comments, but I think it requires using URLs starting with "pfbid" which I don't know how to get.
