How to fetch details/credentials of logged in user to hit Jira Rest API internally?

[Deleted user]

Hi,

We are trying to build a custom Jira plugin, where we need to fetch all the user names as user selector field and make that field as searchable similar to users and roles section as attached in the screenshot.

To fetch users, internally following Jira API call has been made:

http://localhost:8080/rest/api/2/groupuserpicker?query=p&showAvatar=true

For which logged in user credentials will be used.

Can anyone please help me in letting know how to user logged in user credentials to hit the Jira Rest API's and how to implement user selector field in my custom build Jira plugin?

Thanks & Regards,
