Add Firebase App Check to Website -- 2

Job ID: 33999521

Budget: $10 – $30 USD

I have a flutter web app with a firebase back end.
I enabled app check (to authenticate server requests) for web using recaptcha v3 but I keep getting a permission denied error. I also created a debug token for local host but it didn't work either.
I need a firebase expert, skilled in Javascript, to fix this permissions issue for local host and live website.
I need this fixed asap, thanks.
