#' List Activity History in Databrary Session.
#'
#' If a user has access to a volume and session, this function returns the
#' history of modifications to that session.
#'
#' @param session_id Selected session/slot number.
#' @param vb A Boolean value. If TRUE provides verbose output.
#' @param rq An `httr2` request object. Defaults to NULL. To access the activity
#' history on a volume a user has privileges on. Create a request 
#' (`rq <- make_default_request()`); login using `make_login_client(rq = rq)`; 
#' then run `list_session_activity(session_id = <YOUR_SESSION_ID>, rq = rq)`

#' @returns A list with the activity history on a session/slot.

#' @examples
#' \donttest{
#' \dontrun{
#' # The following will only return output if the user has write privileges
#' # on the session.

#' list_session_activity(session_id = 6256, vb = FALSE) # Activity for session 6256.
