Remove H2 from the “Add a reply” text

Hi guys!

First of all, congrats for the great plugin… I have been looking for something to edit the comments for months!

Just a question about SEO: as I don’t want to place H2 tags in non-relevant sections of my site, how could I remove the H2 from this? https://prnt.sc/nM9334rV53N8

Maybe via a CSS style or something? (I don’t know any CSS coding, but I can paste whatever it is need to remove that H2 if neccesary)

Thank you in advance!
