How to add show/hide button for comments section of posts

Hi, SiteOrigin Team.

I want to add collapse button on some blog posts of my blog. How can I do that?

Actually, There is one article about starting a blog (here) and you can see there is I completely disabled comment section because of I’m unable to add a show/hide button for the comments section.

Let me know if there is a solution.

Kind Regards.
