Securing Blazor WebAssembly Apps

I’ve enabled Google Login for my Blazor Web Assembly Application. Until now, I was using Auth0 dev keys for this. Now I want that keys to be replaced by my keys.

So I went to dashboard / Authentication / Social and in that replaced the client id and client secret, which I obtained from Google console

Now when I try to test the application by clicking on the button “Try Connection” I get the error

“Error 400: redirect_uri_mismatch”

Can you please help with what is wrong with the configuration?
