Unity Facebook API read page comments on a post

I have been going through the graph api of facebook but have had a difficult time discerning on how to extract comments from a user’s post in their Facebook page. I understand that the user needs to first log in through the unity app to gain an access key, but I am confused as to how to read page comments, along with identifying username of those making the respective comments. Any idea on where I should start to get this accomplished? Thank you

After awhile I ended up figuring out how to navigate around Facebook’s Graph API. I did this by sending a GET HTTPMethod to a specific Facebook post and deserialized the JSON info Facebook sent to my Unity App. Now my only issue is waiting for Facebook to approve certain app permissions, which may take awhile due to COVID.
