Here it is. We use AddOpenidConnect because our framework is so old. If I can get it to work with this then good, because I don't have budget to update the framework or modules right now. We have tried this same flow with a site we have that was built on 7.x with OpenIddict and it works just fine.
context.Services.AddAuthentication().AddOpenIdConnect("OpenIdConnect", "Azure B2C", options =>
{
//options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
options.Authority = "[https://\<tenant>.b2clogin.com/](https://%3Ctenant%3E.b2clogin.com/)\<domain>/\<Flow>/v2.0";
options.ClientId = "\\\<client>";
options.ClientSecret = "\<secret>";
options.CallbackPath = "/signin-oidc";
options.RequireHttpsMetadata = false;
options.SaveTokens = true;
options.GetClaimsFromUserInfoEndpoint = true;
options.ResponseType = OpenIdConnectResponseType.CodeIdTokenToken;
var scope = "openid \<client> offline\_access email";
options.Scope.Add(scope);
options.ClaimActions.MapJsonKey(ClaimTypes.NameIdentifier, "sub");
