Multiple H1 Tag on Doc pages

Hi, on a documentation page, the ‘How can we help?’ modal header is marked up as <H1>. (see image)

However, the doc itself has an H1 tag used already. Since this modal is not a separate page and is just hidden until the link is clicked, its H1 is also tracked by SERPs.

Thus, this is causing a ‘Multiple H1’ tag issue. Please change that to H2 or lower so that the hierarchy of the doc is maintained. Multiple H1 tags on a single page are frowned upon by SERPs.

I believe the code for this modal is in the following file:
wedocs/templates/content-modal.php

(Right now we have implemented the change as a custom modal on our theme. But it would be great if this could be fixed within the plugin itself.)

Thanks.
