Azure AD B2C MFA Call option for DisplayControl

Question

I am trying to implement MFA phone call support. I have set the meta-data to use "mixed"

 <TechnicalProfile Id="PhoneFactor-Verify">
          <DisplayName>PhoneFactor</DisplayName>
          <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.PhoneFactorProtocolProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
          <Metadata>
            <Item Key="ContentDefinitionReferenceId">api.phonefactor</Item>
            <Item Key="ManualPhoneNumberEntryAllowed">false</Item>
            <Item Key="setting.authenticationMode">mixed</Item>
          </Metadata>

but I still see sms option. The technical profile which DisplayControl calls is as follows:

 <TechnicalProfile Id="AzureMfa-SendSmsSimple">
          <DisplayName>Send Sms</DisplayName>
          <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.AzureMfaProtocolProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
          <Metadata>
            <Item Key="Operation">OneWaySMS</Item>
          </Metadata>
          <InputClaims>

I am guessing, I need to create a new "ValidationClaimsExchangeTechnicalProfile" which will reference a new "TechnicalProfile" with operation for call or something, but I don't see that in any documentation. Can someone please share a sample or documentation link to create operation for call.

Displaycontrol doesn’t support call option. You have to call phonefactor technical profile directly from user journey as per the B2C starter pack.
