Xray custom fields are not shwon on Confluence when creating Test issues

We would like to make the field "Test Type" mandatory and also use the Jira issue creation functionality from Confluence directly, due to this limitation - https://jira.atlassian.com/browse/CONF-32906 , we are not able to make this mandatory.

So we decided to make this field mandatory during the issue transition in the workflow, unfortunately it does not work after making the "Field Required" in the validation, we also use Script Runner plugin and that's not helping either when I try to run a value check

cfValues['Test Type']?.value == 'None'

Can you please advise on how to work around this challenge ? Ideally if we can make this available during issue creation from Confluence that would be awesome..
