Clarification on updated reporter field autoCompleteUrl in Jira API.

[ServiceDesk Plus]

In Service Desk Plus, we have integrated Jira to create Jira issues directly within our application. We are retrieving the field metadata using the following URL:

/rest/api/3/issue/createmeta?projectIds=project_id&expand=projects.issuetypes.fields

Recently, we noticed that the "reporter" field's autoCompleteUrl has changed to:

https://flow4.atlassian.net/rest/api/3/user/recommend?context=Reporter&issueKey=

What should we include after the issueKey? Should we provide the projectKey and append the user input search query like this: &query=${user_input_search}?

Additionally, is there a possibility that this autoCompleteUrl may change again in the future?
