Is there a service with which you can draw a circle (radius) over a point on Google maps?

Question

Google Maps

All the best.
Help me please!
The task is to put on Google a map of points with a radius of 100m and 500m. There are 300 such dots.
I found that you can create your own maps by downloading the KML ball. I found a service that generates this KML kml4earth.appspot.com/circlegen.html
But here each point is created separately and by coordinates, and for 600+ points it's too long ...
I'm looking for some kind of option or service so that I can at the address or at least by coordinates, but in one KML file
P.S. I found this https://www.easymapmaker.com , it seems to be what you need, but the radius there is only from 1 km, and I need 100 and 500
