How to know the id and the title of the added market - google maps

[ElMaxicero4 (YoMaxi Company)]

I use json format
example:

Google Maps - Multiple Markers & Info associated with them

I believe that the code that is required for this to work looks something like this [Sem título] ( i found it in this thread :Get Marker Title from Google Maps component - #2 by ImranTariq ) The problem is, I don’t get how can I connect lat & lng to a specific marker. Example : [blocks] [blocks(1)] How do I connect Items from different lists to a marker ID in order to display specific locations (with lat & lng) when the app opens?
