Any Rest API can used to update the Confluence Page comments

[Shunxu Guo]

Hi Support team,

I can use the rest api to add comments to a page, but not found any api from official document to show how to update the existing comments.  Some question :

1) is there any api can used to update the comments ?

2) for create comments, it looks show the user(createdBy) is the api call user, can we modify it as the real user?  eg. on some page,  user A add some comments, when we copy this page to another confluence use API, then  the comments also want show as user A created , so how we can do it?
