How to change “Leave a comment…” from H4 to P?

Hello Team,

Happy New Year!

On a post where there are existing comments (Example: https://charbelnemnom.com/secure-azure-file-shares-entra-private-access/), the “Leave a comment…” href #respond link with the class=”smooth-scroll” is set to <h4>. I need to change it to <h3> or <p>.

<h4><a href="#respond" class="smooth-scroll">Leave a comment…</a></h4>

Google Pagespeed is complaining that Heading elements are not in a sequentially descending order.
See attached screenshot for more details: https://app.screencast.com/QvESqNSXcvrqy

I already have the following filter to change the default “Leave a Comment” text, but not the headings.

add_filter( 'generate_leave_comment','tu_custom_leave_comment' );
function tu_custom_leave_comment() {
    return 'Let us know what you think, or ask a question...';
}

I came across the following topic: https://generatepress.com/forums/topic/help-with-changing-a-heading/, which applies to the custom text “Let us know what you think, or ask a question…“, but it does not apply to the “Leave a comment…” above.

Your help is highly appreciated.

Thank You!
