他人の投稿への返信を自動的に非表示にする方法

Hello, since I am using Discourse to build a PTE learning platform which has many questions.
I found it might not be well if showing other students’ responses when answer a question. So how to automatically hide others’ post replies in the beginning? and they can choose to open the replies if they want to check other students’ answers.

Here is a question example.

Thank you!!

This reminds me of a plugin my friend and I wrote to allow certain groups of people to collapse other people’s posts.
