Return more data to the client with the bearer token using OAuth token generation WebApi

Question

Is there any way to return more data to the client with the bearer token? I have written the below code using OAuthBearerAuthentication but unable to return more data. I am only getting "token", "token-type" and "expires in".

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
        {
            using (UserMasterRepository _repo = new UserMasterRepository())
            {
                var user = _repo.ValidateUser(context.UserName, context.Password);
                if (user == null)
                {
                    context.SetError("invalid_grant", "Provided username and password is incorrect");
                    return;
                }
                var identity = new ClaimsIdentity(context.Options.AuthenticationType);
                identity.AddClaim(new Claim(ClaimTypes.Role, (user.role_id).ToString()));
                identity.AddClaim(new Claim(ClaimTypes.Name, user.user_name));
                identity.AddClaim(new Claim("Email", user.user_email));
                identity.AddClaim(new Claim("Phone Number", user.user_phone_no));
                context.Validated(identity);
            }
        }

I require more information about the user. For example, I have a tbl_user field in the database. Can I include other information about the user to return, other than "access_token", "token_type" and "expires_in"? If not, how can I get the user in the API based on the access_token?

Any help will be highly appreciated!

I just create a dictionary and save the username and userid.

 if (user == null)
                    {
                        context.SetError("invalid_grant", "Provided username and password is incorrect");
                        return;
                    }                
    
                    var props =  new AuthenticationProperties(
                    new Dictionary<string, string>
                    {
                        { "user_id", user.user_id.ToString() },
                        { "user_name", user.user_name.ToString() }                    
                    });
