Auth client_credentials flow /Swagger

[Nameer-Alkhayyat]

Hey, I know this issue is well knowing to the community! But I hope someone found a solution
I am having an issue authenticating using client_credentials flow and SwaggerUI. For some reason, swagger securitySchemes won't allow me to add the audience and grant_type as parameters, and without them, I can not really get an access token form Auth0. However, if I use Global Client credentials (without adding audience + grant_types) then I get an opaque access token but not JWT access token. Any request with opague token will result with the following error!
jose.exceptions.JWTError: Error decoding token headers

my securitySchemas

 securitySchemes:
    oAuth: 
      type: oauth2
      flows:
        clientCredentials:
          tokenUrl: https://auth-server.com/oauth/token
