Unrelated third party apps appearing during user mention

[M Bun]

I am not sure how did I mess up with all of these, but currently the assignable person now includes Slack, Trello, etc. Other unrelated 3rd party addons which I didn't add by default.

Hello @M Bun

Thank you for reaching out.

The displaying of users from third-party applications happens due to the creation of users to integrate other applications with JIRA.

Basically, these users are added with the project role "atlassian-addons-project-access", which is automatically added to all the permissions of your project, including the assignable user permission, as mentioned in the documentation below:

- Add-on permissions update 

In order to avoid these users to appear in your user picker fields, you can follow the steps below:

1 - Navigate to your project > Project Settings > Permissions > Click to Edit

2 - Click to remove the "atlassian-addons-project-access" from the Assignable User permission.

P.S: If you have any application that uses a user to assign issues, you will not be able to accomplish that.

Let me know if this information helps.
