Extended Master secret for TLS 1.3

[Manish Patidar <mann.patidar@xxxxxxxxx>]

Hi

I am using OpenSSL 3. 0.8.

Need some info regarding Extended Master Secret extension. 

I have notice this extension is used for TLS1.2 connection (TLS1. 2  specific client and Generic server) but this extension is not used for TLS1. 3 connection (Generic client and Generic server). Confirmed by using SSL_get_extms_support. 

Does TLS1.3 supports Extended Master Secret extension? 

Regards
