Enable WWW on website

Hi I would like to know which CNAME record do i need to add/configure

currently when i go www.domain.com it redirects to domain.com and hides the www.

I am not able to do any google ad words as google really wants www.

FYI i also using lets encrypt ssl cert i hope that is not the one causing the issue

Please find the image above with both the cname records
A record which points to the hosting
cname record for www redirection

Thank you

That DNS format doesn’t look familiar. Where are you configuring these records?
