How to add a new Tab into spring boot application endpoint tabs

We have some customized endpoints to help developers debug and test spring boot applications, but currently developers can only access this endpoints via rest. the large Json makes the endpoints very hard to use. So we hope to add an endpoint tab.

I decompiled the spring-boot-run, but it seems that all tabs are currently created in the SpringBootApplicationEndpointsTab. Is there any idea to add a new tab into that?
