Passing Arrays to Verge3D

I had a look at the documentation section but I couldnt find detailed info about getting arrays from the UI.

I am passing

[
{
‘ID’: 1,
‘Number’: 1,
‘Anchor’: ‘POI_001’,
‘Color’: ‘#008000’
},
{
‘ID’: 2,
‘Number’: 2,
‘Anchor’: ‘POI_002’,
‘Color’: ‘#313295’
},
…
]

Right now i am calling a function within Verge3D and I can see that the data is there but I can only see indexes. Loop index also works but I cannot extract the keys. I am not sure wether a LIST or DICTIONARY is an array in the puzzles. Is there any example?

Thank you!
