Does OKTA supports Authorization Grant Type as Assertion?

Hi Expert,

Does OKTA supports Authorization Grant Type as Assertion ?
meaning :
User assertion : self generate using JWT and only add standard claims.
This JWT will be signed by private key to request for Access Token.

grant_type=urn%3Aietf%3Aparams%3Aoauth%3Agrant-type%3Ajwt-bearer
From my reading on the OKTA’s doc and I did not find any information around this area.
I want to assume that OKTA does not support Authorization Grant Type as Assertion.

grant_types_supported
0 “authorization_code”
1 “implicit”
2 “refresh_token”
3 “password”
4 “client_credentials”
