How do I customize my Azure AD B2C sign-in user flow email MFA verification template?

I have built a web app and hosted it using Azure App Service and I am using Azure AD B2C for its authentication method for which I have MFA enabled through email. Is there a way to modify the banner and logo at the email verification template that is currently set to default by Azure AD B2C? I have included an image below where I wish to change the top blue color and the CONTOSO logo at the bottom.




I have taken this snapshot from this link:

For which they mentioned the following:


You can use the company branding feature to customize the content of verification emails. Specifically, these two elements of the email can be customized:




*

Banner logo: Shown at the bottom-right.


*

Background color: Shown at the top.






The email signature contains the Azure AD B2C tenant's name that you provided when you first created the Azure AD B2C tenant. You can change the name using these instructions:




*

Sign in to the Azure portal as the Global Administrator.


*

Open the Microsoft Entra ID blade.


*

Select the Properties tab.


*

Change the Name field.


*

Select Save at the top of the page.






But I seem to not be able to find the following settings in the Azure AD B2C company branding, I could only find the options to customize the sign-in page look by setting the sign-in page background image, banner logo, sign-in page text, sign-in page background color, and square logo image.


I have tried looking into my Azure AD B2C company branding tab and my Microsoft Entra ID company branding tab, but I am unable to find the following customization options.
