/**
* Retrieves event history for the specific visitor using the given filter, returns a promise with visitor history response.
*
* @param {string} visitorId - Identifier of the visitor
* @param {VisitorHistoryFilter} filter - Visitor history filter
* @param {string} filter.limit - limit scanned results
* @param {string} filter.request_id - filter visits by `requestId`.
* @param {string} filter.linked_id - filter visits by your custom identifier.
* @param {string} filter.paginationKey - use `paginationKey` to get the next page of results. When more results are available (e.g., you requested 200 results using `limit` parameter, but a total of 600 results are available), the `paginationKey` top-level attribute is added to the response. The key corresponds to the `requestId` of the last returned event. In the following request, use that value in the `paginationKey` parameter to get the next page of results:
*
* 1. First request, returning most recent 200 events: `GET api-base-url/visitors/:visitorId?limit=200`
* 2. Use `response.paginationKey` to get the next page of results: `GET api-base-url/visitors/:visitorId?limit=200&paginationKey=1683900801733.Ogvu1j`
*
* Pagination happens during scanning and before filtering, so you can get less visits than the `limit` you specified with more available on the next page. When there are no more results available for scanning, the `paginationKey` attribute is not returned.
* @example
* ```javascript
* client
* .getVisitorHistory('<visitorId>', { limit: 1 })
* .then((visitorHistory) => {
* console.log(visitorHistory)
* })
* .catch((error) => {
* if (isVisitorsError(error)) {
* console.log(error.statusCode, error.message)
* if (error.status === 429) {
* retryLater(error.retryAfter) // Needs to be implemented on your side
* }
