How to delete support post?

How can I delete my support post on : https://ww.wp.xz.cn/support/topic/not-hiding-custom-admin-ajax-php-url/
?

Furthermore there should be an option to delete your post, and editing those older than a day! For example, I posted the wrong information on the post above and now I really want to delete it. I believe it has some sensitive information on it, that I want to keep private. I didn’t realize there is no option to delete a post until now.

So, can I this post be deleted please.

Cheers
