Custom object properties as attribute in geometry node

I need a help.

How to use / import object custom properties value into Geometry Nodes.

I used BlenderGIS addon to import a shapefile into Blender.
My shapefile have attribute that descibes for ex. building height, amount of floors etc. But it could be also height of every single tree in a region. Anyway…
I can access custom properties of object with data and values.

I am trying to use Geometry Nodes to play with that values. Is there any node / transforemer that makes it possible to access values from custom object into attribute value of geo-node?

If you can help somehow - all tips will be appretiated

Hi, you should be able to create drivers from your object properties to your geometry node tree
