I have a standard pre-chat form for Salesforce Embedded Chat that I would like to add some introductory title text to. I know this can be done by changing the pre-chat form to a custom lightning component, but for the sake of simplicity, I'd like to avoid resulting to a custom lightning component if possible.

Here's a screenshot of the text I would like to add to the form, before the fields. Currently, I am using an image for this, the text you see on the blue background is actually an image.
