Service Desk API requests take too long and there are frontend timeouts

Requests to the Service Desk API take too long (because of API implementation reasons they can't be done fully parallel). Atlassian Ecosystem Support was contacted and they created a suggestion https://jira.atlassian.com/browse/JSDCLOUD-13526 so that we're able to get the fields we need only and not get the full requests data (similar to what is done in Jira cloud rest api for issue search).
