Please show a meaningful message on Confluence when the user is not able to use the function "create issue" due to some errors on the Jira settings.

For example:

1 -  I get the following error when creating a Jira issue on Jira:

Assignee: The default assignee does NOT have ASSIGNABLE permission OR Unassigned issues are turned off.

2-  I try to create a Jira issue on Confluence with the "Create issue" feature with the same Jira settings of point 1:

Outcome: I expect to have a  warning message on Confluence as well. However, this doesn't happen and the window just closes without doing anything.

I have described the reported case above of a real case. However, the topic is more general and a warning message should be always shown in case of errors.
