How to get pod exec api doc in apiserver

hello every one, i have a question that how to get pod exec api doc in apiserver

Although I can get this information from the source code, it is not standard and inefficient

I think API server, kubectl and kubelet should have detailed API documentation. I read it carefully in the official document, but I didn’t find the API information about pod exec

I hope someone who knows me can give me some advice. Thank you
