Replace IdentityServer with Openiddict in .NET 7

I'm migrating my project from using IdentityServer v6 to Openiddict and having a hard time finding Openiddict stuff similar to IdentityServer.

Currently in Identity server, we have Client to represent OpenID Connect or OAuth2 client:

 new Client
                {
                    ClientId = "client_example",
                    AllowedGrantTypes = GrantTypes.ResourceOwnerPassword,
                    ClientSecrets = clientSecret,
                    AllowedScopes = new List<string> { "scope_1", "scope_2", },
                    AllowOfflineAccess = true,
                    RefreshTokenUsage = TokenUsage.ReUse,
                    AccessTokenLifetime = accessTokenLifetime,
                    AbsoluteRefreshTokenLifetime = 0,
                    c= TokenExpiration.Sliding,
                    SlidingRefreshTokenLifetime = refreshTokenLifetime
                }

According to Openiddict document, I created a Seeder to seed my Clients:

await manager.CreateAsync(new OpenIddictApplicationDescriptor
            {
                ClientId = "client_example",
                ClientSecret = clientSecret,
                ConsentType = ConsentTypes.Explicit,
                DisplayName = "Client Example Test",
                RedirectUris =
                {
                    new Uri("https://localhost:7002/swagger/oauth2-redirect.html")
                },
                PostLogoutRedirectUris =
                {
                    new Uri("https://localhost:7002/resources")
                },
                Permissions =
                {
                    Permissions.Endpoints.Authorization,
                    Permissions.Endpoints.Logout,
                    Permissions.Endpoints.Token,
                    Permissions.GrantTypes.AuthorizationCode,
                    Permissions.ResponseTypes.Code,
                   $"{Permissions.Prefixes.Scope}scope1",
                   $"{Permissions.Prefixes.Scope}scope2"
                },    
            })

How can i change the AccessTokenLifetime ,AccessTokenLifetime and others related stuffs for each client like what i have with Identity Server.

As the answer to What are the default Lifetime values for openiddict tokens shows, token settings are stored in OpenIddictServerOptions. You can modify the default settings using the OpenIddictServerBuilder.Configure(Action<OpenIddictServerOptions>) method or the various Set...LifeTime methods inside AddServer.

For example :

    .AddServer(options =>
    {
        //Set Lifetime options
        options.SetAccessTokenLifetime(TimeSpan.FromMinutes(30))
               .SetAuthorizationCodeLifetime(TimeSpan.FromMinutes(10));

        // Enable the token endpoint.
        options.SetTokenEndpointUris("connect/token");
        ...
    })

The Set methods can be chained because they return the options object.

The same pattern is used for other objects too. If you search the source repository for LifeTime you'll find OpenIddictClientBuilder.SetStateTokenLifetime, fine-grained methods like public static ClaimsPrincipal SetAccessTokenLifetime(this ClaimsPrincipal principal, TimeSpan? lifetime) and more
