Open Google MyMaps, with specifics

Question

I have both a standard Google Map, and Google MyMap working within a portal in FileMaker ... but the My Map is not working quite the way I want. I simply want a URL that I can specify any / all of these parameters:

My Map ID Addr to center on (hopefully with a pin or some indicator) Lat Long is available if needed Zoom = 17

The problem is that when I specify it in My Maps, using

"&q=" with address, and/or, sll= or ll= with long lat

it doesn't center on the address nor the long lat -- and it works just fine if I use standard Google Maps instead of My Map

I've tried specifying the size for the map, but see no difference.

Any ideas how to center the map on the address specified when using My Map?

Thanks! Neil

For my maps, you need to update the underlying map. It does not accept query params in the url as far as I can tell.
