Can't create JIRA issues from Confluence if a mandatory custom field has types textfield, textarea, number etc

When creating JIRA issues on Confluence, only support System fields. As such, we then could not create a Jira ticket from Confluence for Jira projects with required/mandatory Custom fields (which have these field types; textfield, textarea, URL, number i.e. Epic name and Epic Link).

In this ticket we will support JIRA custom field - select list (single choice) if this is required field to input when creating JIRA issues.
