Add support for datetime functions during translation

[jaapa-fens]

When I am writing the following query: match (r:Resource) where r.dt >= datetime('2022-07-04T06:39:33Z') return count(r) as before_count and trying to translate it to gremlin, it shows an error as shown in the image:-

Please, add support to translate the cypher queries with date functions to the corresponding gremlin queries.

Any chance this project can get some help? I'm stuck on the same problem.
