Sorry Stéphane but I was working on other approaches. This is my code that is working :)

import io.gatling.core.Predef._
import io.gatling.http.Predef._

class Next extends Simulation {

  val httpProtocol = http
    .baseUrl("someBaseURL")
    .inferHtmlResources()
    .userAgentHeader(
      "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.61 Safari/537.36"
    )
    .proxy(Proxy("localhost", 8080))

  val jsonFileFeederAdmins = jsonFile(
    "/home/lukasz/Gattling/Skeleton/user-files/resources/data/adminLoginTemplate.json"
  ).circular

  val jsonFileFeederJourneySteps = jsonFile(
    "/home/lukasz/Gattling/Skeleton/user-files/resources/data/userJourneySteps.json"
  ).random

  val jsonadminJourneyStepsSwagger = jsonFile(
    "/home/lukasz/Gattling/Skeleton/user-files/resources/data/adminJourneyStepsSwagger.json"
  ).circular

  val loginHeadres = Map(
    "accept" -> "application/json",
    "accept-encoding" -> "gzip, deflate, br",
    "accept-language" -> "en-US,en;q=0.9,pl;q=0.8",

    "sec-fetch-dest" -> "empty",
    "sec-fetch-mode" -> "cors",

  )
  var token = ""

  def getToken() = {

    repeat(1) {
      feed(jsonFileFeederAdmins)
        .exec(
          http("Login admin and get token")
            .post("/auth/login")
            .headers(loginHeadres)
            .body(
              StringBody(
                """{
          "userName":  "${userName}",

              )
            )
            .check(
              header("set-cookie")
                .saveAs("token")
            )
        )
    }.exec(session => {
      token = session("token").as[String].slice(9, 380)
      println("Token: Bearer " + token)
      session
    })
  }

  def adminJourney() = {
    exec(_.set("token", token)) // Set it here
      .repeat(5) {
        feed(jsonadminJourneyStepsSwagger)
          .exec(
            http("${stepName}")
              .get(
                "${requestUrl}"
              )
              .header(
                "authorization",
                "Bearer " + "${token}"
              )
              .check(status.is(200))
          )
      }
  }
  val scn = scenario("Awesome journey")
    .exec(getToken())
    .exec(adminJourney())
    .pause(10)

  setUp(
    scn.inject(rampUsers(3) during (5 seconds))
  ).protocols(httpProtocol)
}

regex is applied on the response body. You want to use use headerRegex to apply a regex on a response header.
