When trying to update the visitor groups I get 'method not allowed'.

In Startup I clearly allow 'PUT'

services.AddCors(options =>
	{
		options.DefaultPolicyName = defaultPolicyName;
		options.AddDefaultPolicy(policy => policy
			.WithMethods("GET", "PUT", "POST", "DELETE", "OPTIONS")
			.WithHeaders("Origin", "Authorization", "Accept", "Accept-Language", "Accept", "Content-Type")
			.WithExposedContentDeliveryApiHeaders()
			.WithExposedContentDefinitionApiHeaders());
	});

// ... AND ...

app.UseRouting();
app.UseCors();
app.UseAuthentication();
...
app.UseEndpoints...

Is there some configuration that I missed?
