Is your feature request related to a problem? Please describe.
Right now it is not possible to work with the stream requests via this library.

Describe the solution you'd like
The possible solution is to implement an additional SSE client which will include only stream API calls.

Additional context
We need to check the example implementation for the WebFlux SSE.
