How use custom field for my plugin?

Jira Development
1

My plugin is installed with file atlassian-connect.json, in the file, I create 2 custom fields follow Using the issue field module

Custom fields are created, but it’s block, And I must add them in Configure Screen if I want to set custom field for issue.

Do I create and use custom field without ADMIN per?

Same problem here, can create custom fields by JiraIssueFields property in app descriptor atlassian-connect.json or using the /rest/api/3/field REST API, but I want to add these custom fields to the default Issue create view for a specific Project.

What would be the best way to do so?
