ROS 1	`foxglove_msgs/PointsAnnotation`
ROS 2	`foxglove_msgs/msg/PointsAnnotation`
JSON	`foxglove.PointsAnnotation`
Protobuf	`foxglove.PointsAnnotation`
FlatBuffers	`foxglove.PointsAnnotation`
OMG IDL	`foxglove::PointsAnnotation`

You must use the schema names specified above for Foxglove to recognize the schema.
