Deleting cookie from cookie List jar in Gatling 3

Hi I need to drop one cookie from my cookie Jar which I have extracted
below is my code

val ckJar: CookieJar = session("gatling.http.cookies").as[CookieJar]
val CkList = ckJar.get(Uri.create(uri1_azure))

how do I drop/delete a cookies from the CkList?

CookieJar is an internal and not for users.
Why would you want to delete a cookie?
