Any way to support custom type of kong consumer credential

[chenweiqiang7777]

From the SupportedTypes in internal/admission/validation/consumers/credentials/vars.go, it's a list for current supported kong consumer credential type: "basic-auth", "hmac-auth","jwt", "key-auth", "oauth2", "acl", "mtls-auth".
I think they're also the only values we can specify in our kong consumer credential, no matter in kongCredType way or annotation konghq.com/credential way.

I'm writing some kong plugin which has some functional extension of "jwt", I call it "ejwt". But when I specified the konghq.com/credential or kongCredType to "ejwt", it doesn't work and the credential can't be listed by kong admin api (curl -X GET http://localhost:8001/consumers//jwt) even I already defined the daos and schemas for "ejwt" plugin.

So I wonder if there's any way to add custom type of kong consumer credential to enable the kong ingress-controller detect this credential type and load corresponding fields, the same behavior as the official jwt plugin.

Does anyone knows about it ? Thanks in advanced.
