Apache Flink

I have POJO with java.time.OffsetDateTime, which I try to move into table API
```class POJO {
   OffsetDateTime created_at;
}

Table table = tEnv.fromDataStream(stream,
    Schema.newBuilder()
    .columnByExpression("proc_time", "PROCTIME()")
    .build()
);```
It parse the time as RAW
```(
  `created_at` RAW('java.time.OffsetDateTime', '...'),
  `proc_time` TIMESTAMP_LTZ(3) NOT NULL *PROCTIME* AS PROCTIME()
)```
any idea why? the <https://nightlies.apache.org/flink/flink-docs-release-1.19/docs/dev/table/types/#data-type-extraction|documentation> says it should be compatible

I understood OffsetDateTime is not supported yet and the docs are misleading.
I tried to create my own `TypeSerializer&lt;OffsetDateTime&gt;` and annotate the field
```@DataTypeHint(value = "RAW", rawSerializer = OffsetDateTimeSerializer.class, bridgedTo = OffsetDateTime.class)
public OffsetDateTime created_at;```
but now I'm getting:
```Query schema: [created_at: RAW('java.time.OffsetDateTime', '...')]
Sink schema:  [created_at: RAW('java.time.OffsetDateTime', '...')]```
