I need help with custom code I made

Hi guys! ok, so here's my case. I'm using this code in order to show a mandatory checkbox for "I agree to privacy policy" and to show a summary of certain data treatment (my lawyer said it should be there due to GDPR) that's displayed right under the comment box for when a user wants to join the conversation.

add_filter( 'comment_form_default_fields', 'tu_comment_form_change_cookies_consent' );
function tu_comment_form_change_cookies_consent( $fields ) {
	$commenter = wp_get_current_commenter();

	$consent   = empty( $commenter['comment_author_email'] ) ? '' : ' checked="checked"';
	$fields['cookies'] = '<p class="comment-form-cookies-consent"><input id="wp-comment-cookies-consent" name="wp-comment-cookies-consent" type="checkbox" value="yes"' . $consent . ' />' .
					 '<label for="wp-comment-cookies-consent">Acepto la <a target="_blank" href="https://mesquefisio.com/politica-de-privacidad/">política de privacidad.</a></label></p>
					 <details class="proteccion-datos"><summary>Haz click aquí si quieres leer más información sobre Protección de Datos</summary>

</details><br/>';
	return $fields;
}

Everything works like a charm but here's the issue: now I'm doing a multilanguage site and I need this text to be displayed in another language as well. I thought of two possible solutions:

1) Add a conditional in php (I don't know how) to target the language of the page and display one message or another.
2) Convert this whole code in an Element so I can then easily translate it with WPML (I would prefer this option). The problem is that I couldn't find a hook that would work to display it exactly where I want it. Any ideas? Thanks!!
