I am trying to go from the basic Google Maps pin
to a custom one like this 
the goal right here also has a 'blinking' animation.
I have found a way of changing the icon without the animation using Google My Maps, but when I embed this it adds the header of Google My Maps to the website.
Current code in react:
<iframe
title="Our location on Google Maps"
src=""
allowfullscreen="false"
loading="lazy"
referrerpolicy="no-referrer-when-downgrade"
/>
