New admin : Users added via API are automatically granted with Product access

Issue Summary

New user invited via API are automatically added with Product access

Steps to Reproduce

Add a user to a site with the new admin interface using the Jira create user API

curl --request POST \
  --url 'https://new-admin.atlassian.net/rest/api/3/user' \
  --user '<.....>' \
  --header 'Accept: application/json' \
  --header 'Content-Type: application/json' \
  --data '{
  "emailAddress": "testvitecustomer@test.com"
}'

Expected Results

The user created via API is automatically is granted product access based on "New users have access to this product" setting.
The setting can be disabled to allow creation of unlicensed site users (ie. JSM Portal customers).

Actual Results

The new admin is lacking the option to disable "New users have access to this product" in the Product Access settings. The user created via API is automatically granted product access.

Workaround

Please reach out to Atlassian support. Request to disable certain or all product licenses from being granted to new site users added via API.
