Comment moderation is not included in Toolset.
You can display the Comments template (that's where the users submit comments) with Toolset Layouts Cell for Comments.
Or, in a Content Template or View of Posts or even single Post you can show the comment's count.
You cannot submit, edit or manipulate in any form the comments from the Front End, this needs to be done in the backend.
On the front end, you can maximally display the Comment Form (if you have a Layouts theme), or, it's count.
Usually comments are handled by the theme anyway, that is why there is not more features to display those comments integrated in Toolset.
Comments, additionally, are stored in a specific WordPress table, so you cannot connect to them with the CRED Forms, which apply only to the posts table.
I am afraid that this requires custom code, that we cannot provide in the forum, as it is out of the scope of Toolset.
I suggest, if you require help with PHP and custom Database queries, to contact a Contractor: https://toolset.com/contractors/ (Or, to use a Plugin that allows all this)
If you have additional questions about this, please let me know. Otherwise, I think this ticket can be closed.
