How to add google styled map

Hi community,

I’m trying to integrate a styled google map made with https://mapstyle.withgoogle.com/

All they provide is a JSON and a URL where you have to input your API key. I’m not a coder, and I’m wondering where to implement this code in order for this styled google map to work on my website?

Didn’t find my answer in this other old post Integrating a custom google map

There’s a great example using snazzy map Custom Google Maps with Webflow CMS Items - YouTube but this isn’t exactly what I’m after.

Best regards,
Charles C.
