Only 1 big bone appears.

When I use a 'Rigacar' addon in blender 3.6.1, I followed the direction as the tutorials.
But when I add [Armature / Car(deformation) Rig] , I only get one big body-bone unlike the tutorials.

It was supposed to have each wheels have each bones.
But there's no others bones.

I kept doing this many times over and over in a different ways, but the same result.

How can I fix this problem?

I'm using blender 3.6.1,
[Rigacar] version: https://www.youtube.com/watch?app=desktop&v=488NFS4VTP0
Win 10 pro, 64bit

Just found out how to solve it.
By following the advice from the below
https://www.reddit.com/r/blenderhelp/comments/s363y8/hi_i_ve_been_having_this_problem_with_rigacar/

click the whole car objects, and mouse right click/ set origin / origin to geometry.

It helps to generate the rest of the bones!

Leave these for those who got lost like me!
