How to close the finished comments in the docs?

[SWHL]

I installed the giscus in my docs.

Some people have raised questions, and I have also provided answers through Giscus. The corresponding Discussions have been closed, but the docs page still displays relevant comments.

May I ask how to turn off the page displaying completed Discussions?

I found the disscusions, and it says I have to delete this discussion before I can proceed.

I would like to ask if there are any other methods besides this one?
