Tell Google / index sites not to index NOT yet live page

Will be using the webflow hosting, 10 pages will be live, 11th page is not going LIVE until event happens.

So, where do I put the

to stop this page from being indexed?

I’ve looked thru other posts, but didn’t see a definitive… open up This and put in text area.

My guess is ‘Custom Code’ as shown in my screenshot, is this correct?
thanks :wink:
