I know there is a method to merge two Beam Schemas into a new Schema. ( https://beam.apache.org/releases/javadoc/2.26.0/org/apache/beam/sdk/schemas/SchemaUtils.html#mergeWideningNullable-org.apache.beam.sdk.schemas.Schema-org.apache.beam.sdk.schemas.Schema- ).
Is there a similar method for Beam Rows?
