SM3WithSM2 Certificate

Hi,
Using OpenSSL 1.1.1i.

I suppose OpenSSL already supports SM algorithms, including SM2 and SM3.
However, I used the following command on a SM2 certificate,
openssl x509 -text -in test-sm2.crt

and got the below line,
Signature Algorithm: 1.2.156.10197.1.501

This OID is actually SM2 signing with SM3.
Why doesn't openssl x509 tool display this name?
Does OpenSSL support this signature scheme?

Best regards,
John Jiang
