How do you limit a work item being created within the Workflow?

[EASnoblen]

In Jira cloud, company managed software project. 

I'm trying to limit who can create a specific work item type by using the workflow properties.

This work item type is the only work item available in this workflow.

I've added jira.permission.create.group as a workflow property on the Create transition. The value for this property is the group ID from Atlassian admin.

In theory, only users in this group would be able to create this work type after the workflow is updated, but that is not the case. Any user with Issue Create is able to create this work type.  

What am I missing?

@EASnoblen , That's not how you restrict any one from creating issues. Under rules you should see a rule that says "Validate people have a specific permission" edit it and select administer project . That way only project administers will be able to create an issue. 
Have a nice day .

Hi @EASnoblen  - Welcome to the Atlassian Community!

Do I understand you correctly when you say there is only one Work type on the project? Or do you mean there is only one workflow on the project and it is utilized by all of the work types?
