Countdown translation

Hey!! I would like to know how to translate the “days” “hours” “minutes” and “seconds” from the right sidebar countdown.. I’ve tried to change this string

<div class=”dpn-zvc-timer-cell-string”><?php _e( ‘days’, ‘video-conferencing-with-zoom-api’ ); ?></div>

in shortcodes.php inside includes folder but it’s not working.. also I was using loco translate and everything seems to be translated except of this…

Anyone knows what Can I do??

Thanks in advance!!!
