Adding Custom in plugins in Kong Enterprise Edition version 3.0.0

I have added a Custom Plugin on Kong EE in Kong Docker gateway and its working fine. But at the same time I want add a other custom plugin with different functionality so it not showing on the kong UI also it will destroy the previous plugin which I had created.

But there enabled inside the kong-gateway conatainer.
I also shared the Screenshot please have a look on that
As you can see in CLI Screenshot there is mentioned two custom plugins inside docker container

but this image you can see there is no kong-header and Kong-jwt2 header custom plugin in Kong UI Othere Plugins section.

Any Suggestion or Solution for this?
