Change text next previous lesson button

Hi,

Is it possible to alter the text displayed in the next – previous lesson on a lesson page?
Right now, sensei displays the name of the lesson. However, i would like to display something similair to “next lesson” and “previous lesson”.

So far i have:

function override_button() {
	$id = get_the_id();
    $text = sensei_get_prev_next_lessons($id);
	if (is_sensei()){
	$text['next']['name'] = 'Volgende les';
	$text['previous']['name'] = 'Vorige les';
	}
return($text);
}
