Removing text decoration from meta links in comments

Hi There,

I'd like to remove the underline from the meta links (name, date) from comments (example in private info).

I tried both of these but don't work and I can't figure out why:

.wp-block-comment-template a
{
	color: var(--grey-500);
	text-decoration:none;
}

.wp-block-comment-author-name {
	text-decoration:none;
}

Any help appreciated.

A festive cheers!
Paul
