Add new server to HAProxy using dataplane api with Rate limiting in Golang

I am adding new backend server to Haproxy through my golang code. I can see there is a parameter called max connections while adding new server which can be used to limit no of connections. There is also a parameter called maxqueue which will queue the connections if max connection limit is reached. But I cant find-out the option to specify the queue timeout. And I could not find from documentation what is default queue timeout time.

Furthermore, How can I add rate limiting based on no of requests (sliding window) while adding new server to backend?
I can see there is an option of mentioning stick table however I could not find example of its implementation.

I am referring to below documentation.

A server have no "queue timeout". You can set the "queue timeout" via the backend configs

The defaults can be received via the defaults call.
