random displaying topics

Hello guys, I found this plugin. https://github.com/NodeBB/nodebbpluginrandomtopics
and I installed it. But I dont know how to use it. In ACP, it only has two lines.Route to show topics at eq: "featured" or "randomtopics". No leading slash Time cutoff in months, older topics won't be shown. Set to 0 to disable.
Any hints? Thanks.

for example, I have a category called
xxx
, which can be accessed bydomain.com/category/2/algorithm
, so I need to tell this plugin thatRoute to show topics at eq: "featured" or "randomtopics". No leading slash. algorithm
Then,
domain.com/category/2/algorithm
will display topics randomly?I tried. But
domain.com/category/2/algorithm
still display topics as set by users. For exmpleRecently Replied
so only newer topics are picked randomly.
alright, let me try post a new topic.
um, it looks does not work as I expect..

Thanks bro. I tried this:
Route to show topics at eq: "featured" or "randomtopics". No leading slash.
random?cid[]=6Then rebuild and restart.
both the following do not work either:yourforum.com/random?cid[]6
oryourforum.com/random
...I am using 3.7.4.
