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.

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.
