google oidc does not support logout...

Use a different token service for this use case, for example you could put a identityserver4 in between.

@damienbod thank you for your reply.
I am using identityserver3 with below client setting

CLIENT 1:
new Client
{
Enabled = true,
ClientName = "Client1",
ClientId = "Client1",
AccessTokenType = AccessTokenType.Reference,
Flow = Flows.Implicit,
ClientSecrets = new List { new Secret { Value="Client1"} },
RequireConsent = false,

            RedirectUris = new List<string>
            {
                "http://localhost:28650/"
            },
            AllowedCorsOrigins = new List<string>
            {
               "http://localhost:28650/"
            },
            // Valid URLs after logging out
            PostLogoutRedirectUris = new List<string>
            {
                "http://localhost:28650/"
            },

            AllowAccessToAllScopes = true,
            AccessTokenLifetime =  3600
        }

CLIENT 2 :

			new Client
        {
            Enabled = true,
            ClientName = "Client2",
            ClientId = "Client2",
             AccessTokenType = AccessTokenType.Reference,
            Flow = Flows.Implicit,
            ClientSecrets = new List<Secret> { new Secret { Value="Client2"} },
            RequireConsent = false,


            RedirectUris = new List<string>
            {
                "localhost:28550"
            },
            AllowedCorsOrigins = new List<string>
            {
               "localhost:28550"
            },
            // Valid URLs after logging out
            PostLogoutRedirectUris = new List<string>
            {
                "localhost:28550"
            },

            AllowAccessToAllScopes = true,
            AccessTokenLifetime =3600
        }
