Approved apps in ArcGIS Enterprise Portal

[BasWest]

I have created an app and registered it in the Enterprise Portal (version 11.1). Authentication is implemented like in the sample below .

var info = new OAuthInfo({
        appId: pConfig.appId,
        portalUrl: pConfig.domain + "portal",,
        popup: false
    });
    esriId.registerOAuthInfos([info]);

    esriId.checkSignInStatus(info.portalUrl + "/sharing").then(function (r) {
        //console.log (info.portalUrl);
		token = r.token;
        _show();
    }).catch(() => {
        esriId.getCredential(info.portalUrl + "/sharing");
    });

Whenever I start the application while I am in a new browser tab, a prompt appears asking me if the application is allowed to use my credentials

In the portal settings, under security, there is a section "approved apps" in which applications can be registered so that this should not occur. However, registering my app here does not appear to have any effect. Do I need to do something different?
