Webrtc with DTLS 1.3

I'm trying to implement a desktop secure video calling service using WebRTC. As far as I know, it uses DTLS technology, including for establishing an SRTP connection. But the DTLS version 1.2 is used. How can I force WebRTC to use DTLS version 1.3 instead of 1.2?

Wireshark package I use wireshark for package capture, and I see 1.2 version.

Client on Windows 11 has enabled TLS 1.3. Client on Linux has OpenSSL 3.0.2

OpenSSL doesn't have DTLS 1.3 support for now afaik: https://github.com/openssl/openssl/issues/13900

As an additional security level you can consider using end-to-end encryption of WebRTC traffic (Insertable Streams API gives you access to the frames and you can encode/decode them with your own keys). Some code to write, but it looks like an additional benefit of the secure communication app.
