Jira cloud API - how to get users of authorized site

[Michailo Liquidus]

Hello 
I need to retrieve list of users of particular site. I'm using 3LO authorization. All endpoints from documentation returns users from all sites that I have in my organisation. 

I managed to do this for confluence - I used the following request 

GET /search/user?cql=type=user

I need to do the same for Jira. I appreciate all answers. 
Thanks
Mike
