How to specify a custom security scheme name

[forik]

I have an example typespec:

import "@typespec/http";
using TypeSpec.Http;

alias MyOAuth2<Scopes extends string[]> = OAuth2Auth<
  [
    {
      type: OAuth2FlowType.clientCredentials;
      tokenUrl: "https://example.com/auth/token";
    }
  ],
  Scopes
>;

@useAuth(MyOAuth2<["123"]>)
op get(): void;

@useAuth(MyOAuth2<["1234"]>)
@route("/1")
op get2(): Resp;

@doc("Test")
model Resp {
  @statusCode code: 200;
}

This produces the following:

openapi: 3.0.0
info:
  title: (title)
  version: 0.0.0
tags: []
paths:
  /:
    get:
      operationId: get
      parameters: []
      responses:
        '204':
          description: 'There is no content to send for this request, but the headers may be useful. '
      security:
        - OAuth2Auth:
            - '123'
  /1:
    get:
      operationId: get2
      parameters: []
      responses:
        '200':
          description: Test
      security:
        - OAuth2Auth:
            - '1234'
components:
  securitySchemes:
    OAuth2Auth:
      type: oauth2
      flows:
        clientCredentials:
          tokenUrl: https://sandbox.upvest.co/auth/token
          scopes:
            '123': ''
            '1234': ''

How to change OAuth2Auth to a custom value?
And related follow up question: How to add a scope description to components/securitySchemes/scheme/flows/scopes?

If you use model is instead you can achieve that
playground

model MyOAuth2<Scopes extends string[]>
  is OAuth2Auth<
    [
      {
        type: OAuth2FlowType.clientCredentials;
        tokenUrl: "https://example.com/auth/token";
      }
    ],
    Scopes
  >;

So the scheme name would be taken from model name. That works as well probably. Thanks

@timotheeguerin thank you for your response.
I wanted to see if there is a way we can add description to the accepted scopes in a flow. OPs second question.
Let me know if you want me to start a separate issue for the same.
