Help Me About HTTPS

I just registered cloudFlare in Cpanel and It gives me notification cloudflare is enabled. But how can I enable in wordpress or how can I understand it is enabled?

Also as I know WordPress has a plugin for cloudflare, search for it because all you could do on hosting side is done, now it’s up to your software and cloudflare panel
