This control gives provides a means  to add user comments to our infowise forms it works the same as the built-in comments pane found in SharePoint lists views.

When usign this control it is generally recommended to use a container in a 2:1 split mode, placing the whole form on the left and the comments control on the right. This gives a look and feel that matches what you see in SharePoint modern list view pages

But you can design the control on your form to suit your needs.
