#' Get the Events
#'
#' @param con list; required: TRUE; BrAPI connection object
#' @param studyDbId character; required: FALSE; Filter based on an unique study
#'    identifier, in which the events occurred.
#' @param observationUnitDbId character; required: FALSE; Filter based on an
#'    unique observation unit identifier, in which the events occurred.
#' @param eventDbId character; required: FALSE; Filter based on an unique event
#'    identifier.
#' @param eventType character; required: FALSE; Filter based on an event type.
#' @param dateRangeStart character; required: FALSE; Start date for filtering
#'    based on a date range. Coded in the ISO 8601 standard extended format,
#'    where date, time and time zone information needs to be provided (check for
#'    example [https://www.w3.org/TR/NOTE-datetime](https://www.w3.org/TR/NOTE-datetime)
#'    ).
#' @param dateRangeEnd character; required: FALSE; End date for filtering based
#'    on a date range. Coded in the ISO 8601 standard extended format, where

#'    example [https://www.w3.org/TR/NOTE-datetime](https://www.w3.org/TR/NOTE-datetime)
#'    ).
#' @param page integer; required: FALSE; Used to request a specific page of data
#'    to be returned. The page indexing starts at 0 (the first page is
#'    `page = 0`). Default is `0`.
#' @param pageSize integer; required: FALSE; The size of the pages to be
#'    returned. Default is `1000`.
