How to customize Access Token Lifetime Validator using AddIdentityServerAuthentication in WebAPI startup

Question

I have a Web API protected with IdentityServer4. I want to use AddIdentityServerAuthentication extension method to setup protection because I know that it has some features like discovery document caching and so on. But I can't figure out how to customize TokenValidationOptions object to rewrite my custom LifetimeValidator just like the way you do using AddJwtBearer method.

You can't customize your tokens in a API protected by IdentityServer, you can only customize them in the IdentityServer project it's self. Here is the documentation part on tokens. Hope it helps and that i didn't misunderstand you.
EDIT: Maybe this will help:

services.AddAuthentication(IdentityServerAuthenticationDefaults.AuthenticationScheme)
    .AddIdentityServerAuthentication(IdentityServerAuthenticationDefaults.AuthenticationScheme,
        jwtOptions =>
        {
            // jwt bearer options
        },
        referenceOptions =>
        {
            // oauth2 introspection options
        });
