Geospatial support, or with PostGIS extension

[Schelling1989]

1. Does Agensgraph support any geospatial features, something like https://www.arangodb.com/docs/stable/indexing-geo.html ?
2. Or, can I use this extension coordinating with PostGIS extension, and use the PostGIS functions in Agensgraph cypher expression ?

Any document resources will be appreciated. Thanks a lot.
