Hi, What would be the best way to increase the grpc channel size to support writing very large datasets to spicedb? I tried updating the maxInboundMessageSize property for the ManagedChannel but it doesn't seem to help in writing datasets more than 4mb.

//current channel configuration    
val channelSize = 40971520
    @Bean
    fun managedChannel(): ManagedChannel {
        return ManagedChannelBuilder
            .forTarget(spicedbConfigurationProperties.targetUri)
            .maxInboundMessageSize(channelSize)
            .apply {
                if (spicedbConfigurationProperties.useTLS) useTransportSecurity()
            }
            .apply {
                if (spicedbConfigurationProperties.usePlainTextConnection) usePlaintext()
            }
            .build()
    }

Please note that very large writes are not advisable as it would cause contention on the database. For backfilling or initial imports we recommend using the `BulkImport` API

Hi, what led you to conclude that the problem was the gRPC buffer size?
