How to get response headers from RxJS's ajax?

I am creating new frontend for an interview system. Some its API endpoints is updated, so getting pagination info is not a problem, but old ones still have pagination data inside response headers.

P.S. we are using react, redux and redux-observable

RxJS has the following call:

ajax({ ...params }).pipe(
    map(response => { 
        // here I need to somehow get headers from ajax response
    }),
    catchError(errorResponse => {
        // return error
    })
)

I've been looking for the same answer, looks like there is a way (See: https://stackblitz.com/edit/typescript-k2ggm2?file=index.ts):

ajax({ ...params }).pipe(
    map(response => { 
        // here I need to somehow get headers from ajax response
        console.log(response.xhr.getAllResponseHeaders())
        console.log(response.xhr.getResponseHeader('pragma'))
    }),
    catchError(errorResponse => {
        // return error
    })
)
