Error 400: redirect_uri_mismatch when tying from the OAuth 2.0 Playground

Hi Sayontan, thankyou for your support of this plugin over the years.
I am currently trying to authenticate google photos on 2 different sites.
I’m not able to get the Client & Client Secret to save – I am adding and saving but when I go to Authentication the option to Authenticate is not showing.
So I have tried the OAuth 2.0 Playground with the ID & secret. This is when i am getting the Error 400: redirect_uri_mismatch with details being:
“You can’t sign in to this app because it doesn’t comply with Google’s OAuth 2.0 policy.
If you’re the app developer, register the redirect URI in the Google Cloud Console.
Request details: redirect_uri= ”

I have put in the redirect_uri s from the Google Photos tab.

I have checked what I have done against 2 sites where I have the plugin authenticated from a few years ago.

Any suggestions ?
