Completing comments thru python api?

Is it possible to complete comments thru the python api?
Im trying to use:
client.comments.update(comment_id=comment_id,comment_complete=True)

but I keep getting 404 errors for anything using the comments.update() function:
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://api.frame.io/v2/comments/cdf42268-d770-4c02-a405-421619fb5187

I also tried to use:
client._api_call(‘post’, endpoint, payload=kwargs)

but no luck
