I can’t find ‘CPU Thread Groups’ from Unreal Insights.  
I downloaded unreal source from Git (4.24) and build Unreal Insight.  
It’s version is v0.10.  
Click ‘Tracks’ show ‘Quick Filter’ like CPU Track - Y’ but, CPU thread Groups is not there.

What should I do more?

If “CPU Thread Groups” section is not available in the Tracks menu it means the recorded trace does not have cpu events. It looks like the -cpuprofilertrace command line argument was missing.  
In 4.25 this cmd line argument changes to -trace=channel\_name[,channel\_name…]. Ex.: -trace=cpu,frame,log.
