I feel there is some confusion around what has been discussed already about this particular requirement, so I'm going to share a brief summary again.
Option 1, fully interactive map:
The view at /eigendom-zoeken/ is set to show 36 posts/results, per page. If you add a fully interactive map for each post result on this page, it will mean that 36 instances of Google Maps will need to be initialized on a single page load/visit. This will greatly increase the page's loading time and your Google Maps billing cost.
Option 2, Image from Google Maps Static API:
This is the option that Nigel shared in this reply:

Using custom HTML and CSS code, you can get the non-interactive map image from the Google Maps Static API, but, it will still mean, that for each page load/visit, 36 separate connections/requests will be made to the API to fetch the images for each post/result.
This means that this option will also have the drawbacks related to performance and billing costs.

Option 3, saving images from the Google Maps Static API:
If you manage to save the images obtained from the Maps with each post, you'll be able to show them like regular images, without having to connect to Google Maps API, every time the page loads.
If performing this action manually for each property, (as I suggested in my earlier reply) is not feasible, then you'll need to consider hiring a professional from our list of recommended contractors, to see if something like this is possible using custom code:
