how to enable tls1.3 and early data for 0RTT

[ljwhx2002]

I'm using netty-tcnative-boringssl-static with vertx , and trying tls1.3, it works well but I don't know how to enable early data. It was 1 RTT for every reconnection. how to enable 0RTT ?

here is my configuration:

 options.setTcpNoDelay(true)
                .setUseAlpn(true)
                .setTcpFastOpen(true)
                .setSni(true)
                .removeEnabledSecureTransportProtocol("TLSv1")
                .removeEnabledSecureTransportProtocol("TLSv1.2")
                .addEnabledSecureTransportProtocol("TLSv1.3");


 <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-tcnative-boringssl-static</artifactId>
            <version>2.0.53.Final</version>
            <classifier>${os.detected.classifier}</classifier>
</dependency>
