I'm trying to implement reCaptchav3 in iOS but could not make it work. reCaptchav2 invisible works fine. I don't know what's wrong with my code.

HTML head:

<script src='https://www.google.com/recaptcha/api.js?render="SITE_KEY"'></script>

<script>

    grecaptcha.ready(function() {

      grecaptcha.execute('SITE_KEY', {action: 'OnSubmit'})

      .then(function(token) {

        // Verify the token on the server.

        document.getElementById("demo-form").submit();

      });

    });

</script>

Button:

<div class="btn">

  <button class="g-recaptcha" data-callback="OnSubmit" data-expired-callback="OnExpired" data-error-callback="OnError" type="submit" disabled="">Button is disabled</button>

</div>

iOS:

- (void)initWebkitView {

    WKUserContentController *wkController = [[WKUserContentController alloc] init];



    [wkController addScriptMessageHandler:self name:@"reCaptchaiOS"];

    [wkController addUserScript:[self readScript]];



    WKWebViewConfiguration *wkConf = [[WKWebViewConfiguration alloc] init];

    [wkConf setUserContentController:wkController];



    wk = [[WKWebView alloc] initWithFrame:self.view.frame

                        configuration:wkConf];



    wk.backgroundColor = [UIColor clearColor];

    wk.opaque = NO;



    [wk setFrame:self.view.frame];

    [self.view addSubview:wk];

}



- (void)userContentController:(WKUserContentController *)userContentController didReceiveScriptMessage:(WKScriptMessage *)message {

    NSArray<NSString*> *args = (NSArray*)message.body;



    if ([args[0] isEqualToString:@"OnSubmit"])

       [self captchaDidSubmitted:args[1]];

    else if ([args[0] isEqualToString:@"OnError"])

       [self captchaDidError:args[1]];

    else if ([args[0] isEqualToString:@"OnExpired"])

       [self captchaDidExpired:args[1]];

}

Script added in iOS project:

function OnSubmit(response) {

    window.webkit.messageHandlers.reCaptchaiOS.postMessage(["OnSubmit", response]);

}



function OnError(response) {

    window.webkit.messageHandlers.reCaptchaiOS.postMessage(["OnError", response]);

}



function OnExpired(response) {

    window.webkit.messageHandlers.reCaptchaiOS.postMessage(["OnExpired", response]);

}

I used the same code for reCaptchav2 and followed googles guide but I could not get a response.
