Hi @brunocloutier
First, you need to get the API key if you haven’t had it. This page should give you more idea about it: https://developers.google.com/maps/documentation/javascript/get-api-key.
After that, you need to add the API key to ACF settings. You can do it by following this guide: https://www.advancedcustomfields.com/resources/google-map/#google-map%20api.
I hope this helps 🙂
