By default, the output of the map fields (Google Map or OSM) always includes the latitude, longitude, and zoom. If you want only to use the latitude and longitude, please follow this documentation https://docs.metabox.io/fields/map/#getting-field-value.
There is a map functionality on Oxygen Builder where we can put lat, lng and display a map. But because the output of MetaBox location output the zoom I can't use the Oxygen Map functionality.
Is there any way I can output just lat, lng on other variable or map element?
I've been able to do it with ACF but I'm not understanding how to do it with Meta Box. Seems like $field_id is not referenced here - $location = rwmb_get_value( $field_id );
