Unable to hide the Sign Up link in the login form using custom policy

[anandsowm]

As per the general suggestion, I added the setting below in the custom policy to hide the Sign Up link that is shown by default in the login screen. Since our business app will add users via MS Graph API, we should not allow user to sign up themselves.
<Item Key="setting.showSignupLink">false</Item>
But with this custom policy change, the sign up link is continued to be shown. What is the right way to address this?

Hey @anandsowm, here's what has worked for me: in the TrustFrameworkExtensions.xml file inside <ClaimsProviders>...</ClaimsProviders> add the following section:

        <ClaimsProvider>
            <DisplayName>Local Account</DisplayName>
            <TechnicalProfiles>
                <TechnicalProfile Id="SelfAsserted-LocalAccountSignin-Email">
                    <Metadata>
                        <Item Key="setting.showSignupLink">False</Item>
                    </Metadata>
                </TechnicalProfile>
            </TechnicalProfiles>
        </ClaimsProvider>
