Updating/ Modifying the user information(like username, email, display name) on Jira cloud Instance

In Jira server we are able to update or modify the user information (like username, email, display name). But in cloud there is no API to do so. If you have any solution let me know.TIA

In cloud you’d have to use https://developer.atlassian.com/cloud/admin/user-management/rest/ - however it’s not available for jira apps.

@danielwester thanks for your answer.
