WordPress comments – how to check if comment still needs to be approved?

I created a comments.php template and which contains the following code:

The callback function for the wp_list_comments is only relevant for each individual comment, so I didn’t include it here.

The comment form all works as expected. However, I now have a problem with the moderation. When a user adds a comment, it is not visible directly. (I didn’t research if users can change this behaviour, but I guess they can.)

I want to add some text to show to the user after posting the comment that the comment first needs to be moderated. How can I show this? Or, better: how do I check after a comment is submitted, if this comment first needs to be moderated (or not)?

What is the best way to incorporate this message in a comments.php template?
