Question

Yandex maps

Hello! There was already a similar question, but there is no answer.
There are several markers on the map. It is necessary, by clicking on the button, from the attributes of which the coordinates are obtained, to find (select) a label by these coordinates using the API, in order to further perform various manipulations on it. Prompt, please, towards what method to dig. Thanks

How do the markers get on the map? Or look for them in the original list, or add them to GeoObjectsand search in it. Search by comparing coordinates.
